DWF50 Eco and Fast lights flashing

[grazzamongrel]

hi heres the breakdown of what happened, i attended a DWF50 with no heat and tested heater which was ok so came to conclusion that the module was at fault. I replaced it and fixed the heat problem but now at the end of a wash which seems to go through ok the ECO and FAST lights are flashing, and as i said the customer says that the wash seems to complete ok and before i replaced the module everything else was fine (circ motor etc) except no heat.

The faults listed for this are circ motor, module, filters blocked so any help pointing me in the right direction would be greatly appreciated. I am thinking that the module i fitted may be faulty but strangely enough completes cycle and all components seem to be performing just as they should?! 😕

Pressure switch in the up tube from the circ pump can cause this.

pressure switch as in blockage in it or the actual part being at fault? i found it a bit confusing as it didnt show as i fault before i changed the module. 😮

also can i add that i fitted part number C00094686 for the module but see on connects site that it lists 2 modules this being one of them, could it be the module i fitted is wrong?

Before serial number 31017.0000 PCB is the one you have fitted.
After 31017.0001 its a C00143207.

any input on the pressure switch situation? In all my years even as a hotpoint engineer i never had to replace or even look at the pressure switch as a possible cause for any faults.

But this is an Indesit we are talking about, don’t get many D/W pressure switch problems though. 😉
