Hi,
Would anybody be able to tell me what reading (ohms) I should be seeing across the spade connectors of the thermostat/feeler (unplugged). Our dishwasher is not showing any faults, but the temperature is very low inside (above ‘tap’ temperature, so seems to work a little).
I have checked the heating element, and it is not open c’ct, with a resistance of about 25 ohm (if i remember correctly).
There are no faults showing, and it goes therough a complete cycle on all settings. I therefor suspect the thermostat, as it measures 55 K ohm at room temp.
Thanks in advance

There’s three versions of that machine, it’s a Whirlpool essentially, so we’d need the 12NC number to be sure what we’re talking about.
However, there’s no tech on it within the old MFI information, no shock there.
If it’s a thermistor though the resistance should change with an increase or decrease in temperature so it should be fairly easy to check. I have to say though, they’ve not proved to be an issue on those machines.

Hi,
thanks for the reply
The numbers on the side of the washer are
Service 8545 002 15820
Ser 33 0320 010831the resistance does drop when the thermostat is in hot water, but in the 1000’s of ohm (K ohm) doesnt this seem a little high ?

The old style ntc at bottom use to play around alot there were two types from memory . if there was a heating problem i would allways go for ntc if was the older version and replace it with the block connection ntc they made this change around 3 to 4+ years ago i think. my brain has gone dead on me at this point but i think the older version had spade connection and new ones the push on connection block.
my guess is
ntc most likely plus comes with new conection block and wire or use toall else fails new user board
Re: Diplomat ADP 8332 thermostat values (washer not heating
I have removed the ntc (‘old’ style with 2 spade connections on it) for testing. It is not open c’ct, but a high (VERY HIGH) resistance ( in the thousands of ohm ie Kohm). What is a ‘average’ reading I should be seeing for the resistance at room ish temperature for one of or similiar to these thermostats ? These are about £40 ish, so would prefer to prove it has failed, instead of wasting money buying another. I am unable to source one to test without actually purchasing one.

55 kOhms at room temperature is acceptableish, you should get about 25 kOhms at 40c (Just warm it in your hand and wait….)
If the temperature sensor is out of range, the pcb should pick this up and show an error code (Constant flashing). The sensor itself is a notoriously fickle beast.
Check resistance through heater and connectors for burning. May be worth checking for broken wiring in the door at the hinge point.
Stay safe, power off first.

Re: Diplomat ADP 8332 thermostat values (washer not heating
Thanks for the details regarding resistance values. Will check the wiring as suggested. Heater checks out ok with multimeter, but want to bring my Megga home from work to try and see if it is breaking down when given a test at higher voltage.
Probably going to look on Ebay at local dishwashers also, in case one is cheaper than buying spares for ours though !!
If I ‘get to the bottom’, I shall post what findings I have made, so it may help others. Any other suggestions still welcome though.
