Bosch dishwasher cycle problem

[David Martin]

I recently started having a problem with my Bosch 2-year old dishwasher (SHU5315). When the time left indicator LED gets to 1 minute left, it just keeps going and going and never stops until I manually cancel the cycle. It does this on all wash settings except for the 9-minute rinse setting. Has anyone else ever encountered similar behavior?

After searching through misc.consumers.house, I have seen some posts which suggest that the heat sensor needs to be resoldered. Only, not having a schematic of the washer, I am not sure where the heat sensor is. Does anyone know how to get technical information about Bosch appliances?

Thanks in advance for any help.

You've got a 1000 dollar appliance there, more or less. Maybe the thing to do is pay the service man to come out and fix it.

The heat sensor should be someplace in contact with the water in the tub, I would think. Locate it and follow the wires back to the controller. Now why the heat sensor would prevent the wash cycle from ending I don't know. Or is this a sensor that tells that the dishes are dry by the increase in temp? In that case it would probably be at the top of the unit.

The wiring diagrams for appliances are often taped to the back side of kick panels. That's where I found the diagrams for both my JennAir range and KitchenAid dishwasher. Both appliances had service information and diagrams in plastic bags hidden behind these panels. The material for the DW outlined the key sequence that put the unit into diagnostic mode and explained the procedure.

If you are able to diagnose the problem, you can find parts at

They have a heater unit with sensor for $98 and a program control module for $142. ?RccPartID=820940

David,

I had exactly the same problem. I called Bosch and they sent someone out to repair the dishwasher and at no charge. It seems there is a board that can go bad on these machines, especially if one runs in "power scrub" mode often. I can't say enough about Bosch customer service, and recommend you try to call before you attempt a repair. Good luck.

The schematics for my Boash were folding up in the front of the base tray. They are right though- You have a big bucks dishwasher. I'd at least call Bosch and explain the problem.

Hi,

Usually a bad control on the ones we have seen...

control module

Behind the lower access panal is the wire diagram, they are hard to follow at the best of times.

Bosch recomends replacing the module rather than repairing it, that module should have a 5 year parts only warranty from your purchase date.

Yes, bad control module. Probably still on warranty. I had mine replaced for a similar malfunction. It can take a while to get the part, and will be a two-trip repair -- once to diagnose, once to fix. It would have been very pricey if out of warranty.

They sure are expensive. Quiet, and hold a lot, but expensive.
