Hotpoint WF 560 Query

I have just fixed a problem with the above (blocked sump filter) and I’m testing it ready to re-sell and noticed that when a wash is selected the powder isn’t getting flushed from the dispenser.

I watched with the drawer removed and water is flowing from the left hand side into the pre-wash compartment even though pre-wash isn’t selected.

Already checked that the inlet valves are wired correctly and when pre-wash is selected water stills flows into the pre-wash compartment suggesting that the valve wiring isn’t reversed.

What could be causing this?

Quick update

Selected program F

Machine fills but bypasses detergent drawer (pre-wash light off)

Wash cycle starts and water heats.

After about 10-15 mins machine drains then re-fills this time with detergent but according to the lights it’s still washing not rinsing.

I’m puzzled!

Me too, but looking at the wiring diagram it shows that the prewash valve (blue connector block and wires) goes to terminals 4 & 6 on the J8-RAST connector block on the PCB. The main wash valve (white connector block and wires) goes to terminals 1 & 3 on that same J8-RAST connector block.

HTH? 😀

Thanks Martin…I thought you might answer!

I think I’ve fixed it now.

Reading a service manual for a different model it seems that the machine is supposed to allow 1.5 litres of water in through the pre-wash compartment before the main fill. (something to do with the sump float and saving detergent).

It seems that the pressure switch was detecting this first 1.5 litres and turning the heater on but not allowing the main fill.

I’ve replaced the pressure switch with oneI’d taken out of a scrap machine and it’s now working perfectly.

It now fills for about 5-10 seconds through the pre-wash compartment then pauses and continues filling through the powder drawer.

I must remeber this one!!
