Re: NTC error code after belt drop off repaired
I have reconnected the module, unfortunately my repair did not resolve the issue. It could be one of the relays, but since I urgently need the machine, I just ordered a used one (programmed) from eBay. It should be with me by tomorrow.
Re: NTC error code after belt drop off repaired
I have removed the power module. After visual inspection the first thing I noticed that there was a burned crater on the PCB between two of the edge connector pads, proving that there was an arcing between the two pads. Since there is a significant distance between them, the only possible way it could have happen if it did get wet.
So I think you were right about that. :tup:
By the way, “coincidentally”, the two edge connector pads are connected to the dryer’s fan.
I have ground off the soot and filled up the crater with a viscous adhesive as it has burned under the pads and may cause mechanical connection issues in the future.
Once I had to take the power module apart, I thought it would be worth to go through the least longevity friendly parts, the electrolyte caps. One of them, a 470uF cap has a bump on the head, indicating gas build up inside during operation. My ESR meter reads 6.6{e5d1b7155a01ef1f3b9c9968eaba33524ee81600d00d4be2b4d93ac2e58cec2d} loss through it, confirming that it is dying. I have an exact replacement part, so I am going to replace it as soon as the glue has bonded.
I’ll let you know the result, so others might learn something. 😉
As for the drain pump, I don’t know how frequently they go bad as I am not repairing them every day, but I did have to repair that in my previous washing machine. In this machine I was assuming drain hose clamp or something like that, so not really an exact pump leakage.
Re: NTC error code after belt drop off repaired
Why did the belt come off?
Apparently a hose organiser clamp came off and the counterweight was rubbing against the hose, causing it drip. I believe it was the wet surface on the pulley that caused the belt to drop off. I have fixed the hose and properly mounted it. Neither the belt nor the pulley are loose by default. The belt itself is in a good condition, though.
About a month ago I did notice some moisture appearing under the machine but I was hoping that it could survive a couple of weeks when I can finally address the issue. Since the moisture never appeared during the washing cycle I assumed it must be the drain pump.
This machine was repaired about a year ago with bearings, lip seal and has been descaled.
The dryer motor running continuously suggests a faulty power module, has the belt hit this when it came adrift?
I also thought of that but I don’t see how could it have been mechanically possible as the power module is right in the corner. I take it apart and have a look.
