Over the last few days had some luxury time, so figured it was time to take the d/w apart... like what am I going to do... break it? just getting it free was a chore... took a day to figure out the "side tabs" had pushed outwards and were blocking it from coming out. Thought I was going to have to remove a cabinet to get it out.
So Google wisdom (not you lot) said it's ALWAYS the FLOAT SWITCH. So okay... says it's a 15 min job. Two hours later I have the dang thing out, still have all my digits and most of my blood. The pins aren't marked, but 5 and 6 should measure 11k ohms on a good thermister at room temperature. Sure enough... 11k ohms. It did only take 15 min to put it back together...assuming it's not going to leak once water goes back in.
So, I go to test what I thought it was... a short/open in the heating coil that's built into the
expensive variable speed motor. I find online it should have about 15 ohms resistance across it. Looks pretty easy... all I have to do is to find the
hidden heater connector.
WTF ... Hidden?
Fortunately, armed with a map, the connector wasn't hard to find at all. But I couldn't get it to come off with my fingers.
No problem, that's why god gifted man with pliers. Frigging thing still won't budge. Okay, two pliers, one for the socket, one for the plug, and using a spare finger to keep the release tab down while in a yoga position reminiscent of the '60s.
If you're expecting a complete disaster right now, raise you hand. Seriously? Well put your hands back down... you look silly.
With a cracking sound it comes free...
Now the good news is, the heating coil measures 15 ohms, so the short may have been in the socket. It's not wet and I don't see any reason it should have shorted... but I suppose if it gets hot enough to weld plastic together it would dry out fast.
I've never seen a plug/socket go before. Do you think this is the root cause or something else? I was thinking possibly the heat from the heating element could have melted it other than a short, but there's all that carbon in there.... what do you think?
