How to clean water pump and diverter valve on Fisher Peykel


Hi Alan.. usually if there is a problem where the diverter valve is not sensed by the machine control, it will throw a fault code and beep and not complete the cycle. There should be a tech sheet under the control panel. Did you make sure you properly re-connected the two orange wires on your new diverter valve?
I certainly have encountered several over the years where the control stops puting voltage to the diverter in recirculate mode.

If you want to be able to use all the cycles on the machine, then you need a new control board. That is part #420094USP and can be purchased from Fisher Paykel Parts direct;

If you need to do laundry in the meantime, use the PERMA PRESS wash cycle, it should work for you, as that cycle does not use the diverter valve.

Also inspect your water pump and make sure it isnot wet or leaky, as this can cause the machine control to either short out altogether or lose functionality on some cycls such as you are experiencing.

I hope this info is helpful to you.

lift the end of the drain hose see if the tub fills and goes in the rinse cycle if it works you have a syphon problem if so make your drain pipe stand longer.

sure lean washer back against wall diverter valve on bottom rear next to pump probably just clogged with lint

I had the same symptoms (washes normally, but won't drain/spin) It would only make a faint hum. I found it fairly easy to lift and tilt back the upper section id by removing the front two screws under the lid. The aggitator came out easily by removing the softener cup and unscrewing the large plastic wingnut inside. The upper plastic shroud came off by carefully removing the eight or so plastic tabs. Once the shroud was off, I could lift out the main wash tub. With the wash tub out, I was able to remove all remaining water from the holding tub with a cup and sponge out all water down into the depression where the pump assembly is located. One screw removed the cover to the pump assembly. Once apart, I found a thin piece of plastic was jamming the pump impeller from spinning. I blew through the drain hose from the back to ensure the drain system was clean. Reassembled in reverse in less than 10 minutes. It worked. Thanks Fixya!!!
