Hi Group!
Preamble: We have a Bosch dishwasher: 9000356727 Rev C. For some strange reason, the manual we have is for the incorrect model and I cannot find anything online -it's from 2015, I can tell from a QA sticker inside. I have contacted Bosch about getting the correct manual. The model number noted here is correct. No typos - I've checked it many times. It looks like a simpler version of this:
Products - Dishwashers - Built-in Dishwashers - All Dishwashers - SGE68U55UC
Same general layout but less options. The options our one has are Heavy, Auto, Normal and Rinse. There's an On/Off button. A delay button. A start button. And sanitize. I think that's all there is (writing this at work from memory).
So with that all out of the way......
In the last week the dishwasher has started tripping the 20A AFCI breaker. From what I can tell from the breaker box it seems to be on a dedicated circuit. The breaker is only tripped during the wash cycle and it always happens after 20 minutes. If I reset the breaker the washer will run some more and then trip again but I don't have timing information on that. If I reset the breaker, reset the washer and restart the wash cycle, it will again trip the breaker after 20 minutes. I have run the rinse program repeatedly without anything being tripped. That cycle runs for 9 minutes. When the breaker trips, there is water left in the bottom of the washer. I either shop vac it out or reset the washer and run a rinse cycle to clear it out. I've removed the meshes and baskets that I can and there are no blockages. Also, since I've run the rinse cycle many times I know the washer is draining properly.
The dishwasher is not hard-wired, it's plugged into an outlet under the sink. I ran a heavy duty extension cord from a different (non-AFCI) circuit and ran the dishwasher on the wash cycle and it completed without incident. I then plugged the washer into a different AFCI outlet (same breaker box), ran the wash cycle and it tripped the (different) breaker after 20 minutes, same as before.
Some additional information. In our kitchen we have the following circuits that are all on AFCI (Siemens and Murray BTW).
1. Microwave,
2. Kitchen outlets (on island)
3. Kitchen outlets (coffee maker) (different breaker box)
4. Dishwasher
We have been in this house for about 4 months and all of those breakers have tripped at some point. Not regularly like with the dishwasher but the coffee maker has tripped the breaker a couple of times recently.
I'm in a quandary now. These breakers are about 40 bucks a pop so I don't just want to arbitrarily replace them all. I spoke with a general contractor friend and he suggested replacing the dishwasher AFCI since he thinks they could all be connected. I have to say that didn't sound right to me since I thought that each breaker was on its own circuit BUT I'm certainly no expert so.....here I am, speaking to those who are experts.
I did read that AFCI breakers can be VERY sensitive and people have problems with them. I might just have to bite the bullet and get an electrician in but figured I would ask here first.
Cheers, Max
EDITS:
1. Every time I reset the AFCI, the ARC led comes on for a moment before going out.
2. I checked the wiring inside the dishwasher junction box and everything is clean. (I did NOT check the wiring behind the outlet, but since the dishwasher trips other AFCIs, this seems moot).
3. The kitchen is new as of Fall 2015. It's unused, the sellers had already moved out of the house before they totally renovated the kitchen.
4. The ice maker in the freezer doesn't work - it appears building a kitchen and not using it for almost a year is not a great thing to do. Quality!
