Hygena dishwasher woes

[scooner_or_later]

Hi,

I’ve got a fairly old Hygena APL8124/1 dishwasher that has given good service but has recently started playing up. The circulation pump stopped working, so I took it out to test it and see if could be repaired, replacement pumps being around 100 quid. The pump is an Askoll M13 which has an electronically controlled motor, so I immediately suspected the microcontoller to have gone. Turns out it was a simple thermal fuse which had failed open circuit, with that replaced with a similar rated device from the junk box the pump worked fine.

Having put the pump back in the dishwasher it seemed all was well, it filled (for a rinse) and the pump functioned correctly, however when it came to drain, the drain pump would not pump out, even though it was turning. I thought it may be an airlock of some sort, so after a bit of fiddling with that I got it to drain, but now the washer is refusing to fill with water. The inlet valve was fine before, has 240V on it when it supposed to open and hums, suggesting the coil is ok but its not opening or water cannot flow for some reason.

Could the pumping and filling problems be caused by an airlock from taking out the circulation pump or when the machine was put on its side?
There must be some kind of trick to bleed the system.

Thanks

Absolutely not, if the inlet solenoid has 240v to it (please don’t live test, it is dangerous and never necessary) but isn’t letting water in then it is faulty…

If the thermal protection on the wash pump has failed then that’s most likely because the pump is about to et go…do a search on here for ‘whirlpool AND askoll’…you’ll find a wealth of information on how they fail and why the conversion kit is the best remedy 😉

Plug out at all times when testing :zap:
