The dishwasher was not heating at all, and when I looked, I noticed the heating element was cracked. I ordered a new one, it still wasn’t heating. I checked it with my multimeter and the ohms were reading way high, so I considered it defective and replaced it again. This newest one is still not heating. Could it be something else?
If so, how do I test to see what it is?
Thanks for any help.
Here are your parts.
Note that it is for a PLYW5.
PLWY6 did not come up.

Could it be something else?
Yes it could.
Unplug the unit and check the hi-limit thermostat.
Should be 0 ohms.
If OK then check at the control board.
P4-4 to P4-3, you should see the heater resistance.
If not you have a bad connection/wire going down to the heater/hi-limit.
Thanks so much. I really appreciate it.

I know this is an older thread, but hopefully can get an answer. I have the WDF530PLYW5 and have been trying to figure out why it’s not heating/drying.
Replaced the heating element, didn’t work. Checked the hi limit thermostat, still good. Checking the board at P4-4 to P4-3, I have about 20ohms resistance. Is this GOOD? You said "you should see the heater resistance". So what else could it be?
Sorry if this is obvious - I’m very limited in my electrical knowledge.
Checking the board at P4-4 to P4-3, I have about 20ohms resistance. Is this GOOD?
Yes it is good.
Spec is 8 to 30 ohms so you are smack dab in the middle.
So what else could it be?
Since the heater si connected directly to the incoming line voltage through two relays odds are high that it is a bad control board.
I would check the thermistor resistance just to be sure it is OK before replacing the board.
See the WATER HEATING/HEAT DRY in the strip circuits section of the tech sheet.
i tested the P4-4 AND P4-3 and i got nothing. It jsut show a "1". The P4-4 and P4-3 are the last 2 connectors on the board to the left, correct?
Yes these connections are 3 and 4 but yoyu are not checking them correctly.
What you are trying to check is the heater and hi-limit so it is the connector that plugs into this that you want to check.
Take a look at the strip circuits in the tech sheet.
Ah yes. Duh. Learning as I go. Thank you. I will check that tonight and report back.
Thanks for the advice. I ended up getting a control board on ******** and the dishwasher appears to be fully functional again.
