Can anyone tell me if I am looking at the right fault codes for a Hotpoint dishwasher FDW20P. It has four LED`s 1 prewash, 2 wash, 3 rinse, 4 dry. 1 & 3 are flashing and looking through the fault code guide I have assumed it is a circulation pump fault.
The pump appeared fine but I had one on the van which I fitted.. same fault. Reset programme! it drrains then Fills for 20/30 seconds then goes into fault mode.. even on other fault codes 1&3 says filters blocked but it doesn`t switch circ pump on? the PCB does look like the 100 bit but was not looking as I was unaware until browsing through the site it was fitted.

Filter blocked
The machine has tried to carry out the filter cleaning cycle but has failed to clear the blockage.
• Check the filter or sump is not blocked.
• Check the pressure switch is not stuck in the empty position (contacts 11-12) or the
pressure chamber or air tube are either blocked, unattached or split.
• Check the high pressure sensor or the connecting hose for blockages.
• Check the wash pump is circulating the water.
• Check the wiring to the pressure switch and high pressure sensor.
• Check the edge connector blocks on the pressure switch and module card.
• Check the outlet hose is not too low causing the machine to siphon.
• If all the above tests are OK replace module card.
