Diplomat 8252 problem

[ckchamb]

Our diplomat has started to play up, we think it tripped the house rcd the other night but can’t be sure. When set to go next day did not appear to want to take water, looked at the inlet solenoid and appeared stuck, freed this off and restarted only for it to the stop on an E2 error later in the program. Now it doesn’t want to wash just goes for a while and then E2 where it is continuously filling and empying. Any ideas? Have read the E2 page and checked for blockages but there doesn’t appear to be any!

thanks

Re: Diplomat 8252 problem

If the matrix on the RHS and the transfer tube are spotless then have a look at the pressure switch. If that’s ok too then it’s probably the pcb i’m afraid, and if it tripped the power out there may be an earth fault which has damaged the pcb 😕

Time to get your meter out…plug out of course. :zap:

If that’s beyond you then you might like to try the link below to find an approved engineer?

Re: Diplomat 8252 problem

Your right a nasty mess behind the 7 pin plug, sensors / switches / solenoid.

Inlet valve reads 3.6K, Pressure switch and flood switch operate ok. Salt sensor ? 0.2Ohm,and rinse aid ? open circuit. The rinse aid? I pressume is a switch but the salt sensor?
what type of components are these? The 0.2 ohm does this sound correct. The board has a nasty black burn on the pcb tracks, disintegrating tracks from C3 and C5 which go to the rinse aid and salt sensors!
Are these components what killed the board, there are slight signs of water damge on the switch / display mini board, nothing that should cause the destruction though.

What price a new board?

Thanks

Both the salt sensor and rinse-aid sensors are reed switches operated by floating magnets…the readings you’ve got are correct if it has rinse-aid but no salt 😉

The water damage is probably the root cause and the pcb’s are not known to be bombproof.

An email to spares@ukwhitegoods.co.uk should get you the price and availability…done forget to include all the model details.
