Customer rang today re above machine. States that no program will work and just the pump runs. He knows it’s the pump as he as had filter off and seen impellor going around.
Any clues??Re: Zan ZWF14070W1
These use a solid state switch, similar to a triac to operate the pump. They sometimes go short circuit. In other words module repair or new module required.
Re: Zan ZWF14070W1
If you have a trade account with Connect Distribution you can view a PDF FILE of the Serice Manual (including DIAGNOSTICS)for machines using EWM1100 electronics by selecting SPARES FOR BY BRAND.
Select the Make then Model. IN THIS CASE ZWF14070W1
In Mediator there is a drop down list one of which is (Service manual GUIDE TO DIAGNOSTICS EWM1100 )PAGE 24 Shows malfunction of Triac that controls the Pump an associated wiring.
Useful for anyone that does no have the TDS DISC

a dodgy pressure switch 1325162038 is likely on these, ive had a few a little tap gets them going again, failing that a new switch usually sorts it.
check the fault code stored in memory it could be e38 or something, i had 1 the other day pump running nothing else checked switch still no joy, i then looked at the code, reset it and it worked again, touch wood not been back since.
