A typical cause is disconnecting a plug after the heater has failed to start without turning off the switch on the controller. It can sometimes be erased by a diagnostic unit. Sometimes the code will not clear and a known fault needs to be introduced i.e. pull the fuel pump wires off and start the heater 5 times, this will move the fault to the end of the fault code memory and then it will be over written as the heater can only hold 5 faults. If that fails replace the ECU.Check alternator regulator or disconnect battery charger. Possibly 12 volt heater connected to 24 volt battery but this could damage the ecu. Usually occurs during starting when glowpin is on. Extremely common fault, usually due to a discharged battery but many other reasons described on our Low Voltage Faults page. The measurement method described in the Eberspacher Airtronic fault code list is almost useless, the heater must be connected and switched on so drawing current. Check heating air path for crushed pipes or blockages, air outlets closed or blocked. Often caused by accidentally puting objects against heating outlets. Check if air pipes are too long or have too many bends. (Just replacing a straight outlet hood with right angle version can often put the piping outside specification.) Check pumped fuel volume. Check Overheat sensor. Check blower fan as fault code 33. The heater can be reset from fault codes 012 and 013 by switching off and back on. Overheating is a serious safety issue and can damage the ECU so find and eliminate the cause before resetting. More info on our Faults Main page, mainly in the Faults when running section. Check as fault code 012. Check Flame sensor instead of overheat sensor. Check as fault code 012. Check both Flame sensor and Overheat sensor. On Hydronic water heaters the code is for 10 overheats in succession). More info in fault code 017. For remedial action see Fault code 012.The ECU is locked for safety reasons.https://www.chinawholesaletown.com/uploadfiles/editor_file/crown-macro-tech-5002vz-manual.xml The ECU failed to recognise overheating fault code 012 or 013. My explanation on why 017 occurs is on the Faults Main page. Heat may have damaged the ECU, if not it can be unlocked using appropriate equipment. IMPORTANT Identify and clear the cause of overheating before trying to reset. This lockout is for a very serious safety problem. More info on our Faults Main page. Check glowpin resistance, 0.42 to 0.7 ohms, 24v glowpin 1.2 to 1.9 ohms. Measuring accurately is not required for fault code 020. For fault code 021 use accurate measurement technique shown on Faults Main page and Airtronic Servicing page 2.Manual gives alternative method but few users will have a suitable high current 8v supply. Eberspacher advise that connecting to a 12v battery might destroy the glowpin but so far our users report they had no problem while doing a short duration test on 12v. Make sure leads include a fuse when testing for 021 code. Caution, glowpin will glow red hot if working ok. Check for water leaking inside heater and on connectors. Check glowpin resistance as in code 020. Check as code 020 Check as code 021 Energy input less than 2000 watts. Check as code 019 Check fan is free to rotate and not catching on anything. Check wiring for breaks, loose connections, faulty insulation. Check combustion air path, both inlet and exhaust, are not obstructed. Blower brushes or bearings worn. If testing motor on a dc supply use 6 or 8v, not 12v.(Measurement as described in D4WSC D5WSC manual is completely wrong) Check resistance of fan motor. Resistance should be approx 0.5 ohms, accuracy not critical for this test. Rotating shaft slowly by hand while checking may reveal faulty segments. If testing fan use 6 or 8v dc supply, not 12v. Check for water leaking inside heater and on connectors. Check motor is free to rotate and not catching on anything. Check bearings are not starting to seize. Check resistance of blower motor which should be approx 0.5 ohms.https://www.informaquiz.it/petrgenis1604790/status/flotaganis20052022-1642 Use accurate measurement technique shown on Faults Main page and Airtronic Servicing page 2. Replace motor. If testing blower use 6 or 8v dc supply, not 12v. Check wiring to relay for breaks or loose connection. Check relay: Disconnect 8 pin connector, measure on the connector part not going to the ECU. Measure resistance between pins 2 and 3. Depending upon type of relay a good reading should typically be around 80 ohms. If greater than 1000 ohms check relay coil resistance or replace relay. Check wiring to relay for insulation damage or broken connection touching. Check for water leaking inside heater and on connectors. Check relay: Remove relay, if fault 038 displayed replace relay. Alternative method: Disconnect 8 pin connector, measure on the connector part not going to the ECU. Measure resistance between pins 2 and 3. Depending upon type of relay a good reading should typically be around 80 ohms. If lower than 20 ohms remove relay. Then if resistance becomes very high replace relay. Check resistance of the water pump, rotate shaft by hand while checking. Disconnect 14 pin connector, measure on the connector part not going to the ECU. Measure resistance between pins 10 and 11. No resistance figure is quoted but probably about 0.5 ohms. If trying pump on 12v battery without water keep test very short. Check for water leaking inside heater and on connectors. Check if pump is running dry. Vent heater, check header tank water level. Disconnect connection in water pump cable harness. If error code 041 is then shown replace water pump. Check for water leaking inside heater and on connectors. Most likely cause is mechanical damage to the insulation where cables are clipped in position or uninsulated connectors on older Eberspacher pump types touching the chassis. Check for water leaking inside heater and on connectors. Disconnect the wires on the pump connector and measure the resistance of the pump. If pump is ok check wiring to pump.http://genlab-sports.com/images/caple-dd600bk-manual.pdf Measure resistance from connector. If no test meter is available the pump can be pulsed with a 12 volt battery. Connect and disconnect from the battery, each time it should make a loud click. (Make sure the pump wiring is not connected before doing this test or you can destroy the ECU. Also take care not to accidentally short circuit the battery). More info Fuel 2 page. Check for water leaking inside heater and on connectors. ECU locked out. Hydronic - The ECU locks out after 10 consecutive start attempt failures. Manual is not clear, I think a failed start with the second start attempt counts as one failure. IMPORTANT Identify and clear the cause before trying to reset. This lockout is for your safety as each attempt leaves unburnt fuel. It can be unlocked with appropriate equipment. Check flame sensor: Disconnect 14 pin connector, measure on the connector part not going to the ECU. Measure resistance between pins 1 and 2. If reading greater than 1274 ohms replace sensor. Unit failed to start on both start attempt sequences. This is simply a standard failure to start fault indication. Most heaters checked will have this code in memory, usually it can be ignored as you will already know when it failed to start, it switched off without generating any heat.

Due to restrictions below the floor line, the heater mounting plate was raised off the floor using custom made brackets. Usually the heater’s mounting plate is installed into the vehicle floor. For anyone interested, here’s a copy of the installation manual. You should conduct your own research and not make decisions based entirely on what is printed here. It’s recommended that any installer first consider the installation in depth, before picking up tools and beginning the project. Unfortunately during winter, it's almost impossible to recharge the battery system using solar power, so prudent use of 12v storage capacity was absolute necessity when freedom camping. I decided to replace my old heater with a modern diesel fuelled model. The advantage is that they are really quiet, small and more importantly, very power efficient. The only disadvantage is that they are expensive. There are also two cheaper diesel heaters brands, more commonly sold in Australia. The Snugger which made in China and the Yeki made in Korea. Both these cheaper units are copies of the market leaders and owner feedback suggests that they should be ignored. The most common complaint is that they’re noisy, unreliable and have a service life of only 2,000 hours compared to the market leader at 5,000 hours. Some marine users report only getting 1,500 hours from the Chinese heater. The heating capacity, fuel consumption and power consumption of both brands is similar (although the Eberspacher is slightly more favourable). After doing considerable research, it seems the Webasto isn't as easy to service and the blower motor design life is shorter at 3,000 hours against the Eberspacher at 5,000 hours. Carbon build up in diesel heaters can be a problem and Eberspacher have thought of a solution. They run their glow plug at the beginning and end of each run cycle to ensure the combustion chamber is cleared of any excess fuel and carbon. A small amount of smoke is produced during this burn off, but it’s barely noticeable. The burner plate on the Eberspacher is larger, which means it's easier to maintain cleanliness.On this particular installation, the vehicle already had existing warm air floor vents ducted throughout the RV. An aluminium plate was made up to block off the rear duct and act as a warm air input point from the diesel heater. Two layers of heat proof cloth were used to insulate the surrounding structure from the warm ducting and also make a snug fit. The cool cabin air (that is yet to be heated) is drawn through an existing vent into the locker cavity so I have left the furnace inlet air vent open and just fitted on the inlet guard. They have thought of most things and you won't need to buy much at all to complete the installation. The kit even came with a diesel pick up point to install into your fuel tank. Its fuel is supplied by a flexible fuel hose which runs from the vehicle’s diesel tank. I decided to tap into this diesel supply. There are usually two pipes; one supplies fresh diesel from the tank and the other takes unused diesel back to the tank. Don't access the return line as typically it contains air bubbles, a by-product of the injector pump process. The bubbles will cause all sorts of problems for your new diesel heater. Once I determined which one was the supply, I 'clamped' the rubber fuel supply line with some vice grips to prevent fuel from leaking after you cut into the pipe. I used an old piece of inner tube to line the jaws of the vice grips so it didn't distort or puncture the fuel line. Next I installed a brass “tee” (not supplied) into the existing diesel fuel line.Consider shielding the fuel pipe at every corner - especially when it comes in contact with the chassis. Old inner rubber tube, or even garden hose pipe can make ideal protection in these circumstances, as seen in the pictures below. It comes with a special rubber holder which dampens the pump noise. It is very important that the fuel pump sits at a 15-30 degree horizontal incline. Eberspacher note this is so any air bubbles can naturally feed from the fuel pump to the heater and not become a source of a fuel blockage. It’s reported that it is almost impossible to see from the outside so is difficult to diagnose. Make sure the fuel hose is supported and kept away from the exhaust. It was not possible to fit the mounting plate into the compartment floor due to restrictions below so I made some support legs to raise the mounting plate. 30mm wide strips of aluminium plate were used and holes drilled at each ends of the plate for mounting to the D4 and securing it to the floor. When using aluminium, always try and make any bends gradual, rather than say at sharp right angles, even though it might take a little longer to construct. Aluminium is quite a soft metal and has a tendency to lose some of its strength, if the bend is severe. Bending the aluminium around a pipe achieves a nice gradual curve and minimises any reduction in strength at the point of the curve. I used paint able to withstand up to 500C temperatures but this was not really necessary. The combustion exhaust will reach temperatures of up to 230 degrees C so you need to be conscious of the heat that will be reflected from it, or transfer to any fitting which hold it. This construction ensures it has an extended lifespan, however, it’s not completely airtight.This allowed the exhaust pipe to be wrapped in heatproof cloth for about 50mm as it passed through the floor area. I used this to pass the exhaust pipe downwards to the muffler location. From here the remaining exhaust pipe took the fumes clear of the RV. The supplied 2m length of stainless steel pipe was more than enough to do the job. By painting the pipe with black spray paint, the internal pipework is almost invisible when looking at it from the outside. The furnace cavity wiring was easy to do. The main wiring loom (A.K.A wiring harness) was prewired with special connectors so the wall controller, fuel dosing pump and heater just clip in. It’s important that the supply wiring from the battery is large enough so there isn’t a big voltage drop while the glow pin is on. I used 6mm cable. The recommended cable size is 4mm for cable runs up to 5m or 6mm for from 5m-8m. I mounted it in the kitchen on the fridge wall cabinet. It’s easy to see and access being in the middle of the RV. The supplied 8m loom wasn’t long enough so it was cut and extended to reach the display unit location. The electrical loom that comes with the D4 has plug connections on either end, so passing these plugs and sockets through wall cavities is not easy. Cutting the electrically colour coded cable was an easy option and made running cable a simple task. I joined the cable afterwards including heat shrink tubing over the connections to make a watertight and snug finish. The controlled just surface mounts to the wall. It consumes very little power and constantly displays the ambient air temperature inside the RV cabin, whether the heater is switched on or off. The temperature display allows you to heat up to a very tropical 30 degrees. It also has the capability to circulate air, without the heater running. A feature that is useful for mainly marine installations. Using a screwdriver of the same I.D of the pipe, push the pipe over the screw driver, mount the screw driver in a vice and then holding the pipe, bend it to the angle required, without crushing the pipe ID. If you need to make sure no exhaust gasses escape (as with this installation because the outlet gas pipes were in the cavity that my cabin air comes from) run a product like Maniseal exhaust sealant on the inside of the pipe over the area which will be clamped to the heater port. After about 30 minutes of open air drying, it can be sanded lightly, making it impossible for any exhaust gases to escape through the inside pipe threaded indentations. When Maniseal is squeezed from the tube, its consistency is similar to toothpaste, but it hardens considerably more when it is heated and then becomes rock hard, like body filler or bog. If you have to fit the combustion inlet and exhaust pipes after the heater mount is screwed to the floor, tightening the clamps can be difficult. Using an angle grinder, it’s possible to cut out a small section of this circular rim so that it’s easier to get a socket in to tighten. It clicks faster depending on the heat required. While most of the vibration is absorbed, some noise escapes. As the heater fan is so quiet when running on low, you may hear the pump clicking away in the still of night. The addition of sound deadening material around the fuel pump can deaden the faint pump noise almost completely. Eberspacher don't recommend running the furnace, despite it being fitted with a filter, when refilling your diesel tanks. The obvious reason for this is that the contents of your tank are being stirred up and you may attract dirty fuel into the filter, which is quite small. Once the set point temperature was almost achieved, the blower speed starts to reduce, as does the amount of fuel used and the heat produced. When the heater dropped down to low mode and had settled into its 'sweet spot', the air temperature coming out dropped down to about 35 degrees C. Occasionally, it gradually increases speed, for about 10 minutes every hour, once it senses it is losing the battle to maintain a delicious 20C degree cabin temperature. Then afterwards it dropped back to low mode again. You will hardly see a drop in your fuel gauge, unless you are using it 24 hours a day. Because of the 5,000 hour expected life cycle, you can install it and forget it (other than a few simple services along the way). The D4 is a great match for my size vehicle.
