I own a Bosch model shu4002uc-06 dishwasher. The problem was that it would not enter into the rinse cycle because the water was not being heated to trip the thermostat. My question is will replacing the "heater asm" part number 264463 correct the problem. or is the a heating element that I can not find on any parts breakdown that needs replacing. Also hard hard of a job will this be for me to complete.

this heats your water
http://www.repaircli...ccPartID=467089
Is it being energized?
Turn off power at breaker and test the heater for continuity.
If it's open, the heater is bad.
if it shows continuity, you have to trace the control voltage.
It may not be fun
I have not encountered this problem, but Bosch can be murder for the home handyman. good luck

Taking apart a Bosch unit is TOUGH for gaining access to the heating element. Its a ral bear so I would advise getting a well Bosch versed guy in to do this

remove the control module and inspect for burnt solder joint. i bet i have repaired a hundred of these in the last couple of years. never replaced an element or a flow switch, it is always the burnt solder joint. just clean it up and resolder.

Denny, I think this in one of those older Bosch's with the good ol' fashioned mechanical timer, before the control board era.

You are right about it having a mechnaical timer. I have the same problem as the other person, that my dishwasher does not want to cycle through all of its washing cycles. My Bosch diswasher is a model number shu 4002uc/u06. The water is plenty hot! When you refer to soldering a poor connection, are you referring to the mechanical timer or some other control panel. Could my thermostate be broken? The washer seems to cycle fine through the wash cycle but "gets stuck" in the rinse cycle. Any suggestions would be apprecated.

I would be looking for a broken wire to the temperature thermostat, or maybe a faulty t/stat. Take the door panel off and look for loose or split wiring :shock: . (as long as I am right in assuming that it wont go past the wash, and the water gets very hot)
please help us to help you, http://www.fixitnow.com/beerfund.htm

I have the same problem with my dishwasher. It's an SMU2042uc/14 model and it get's stuck in the middle of the wash cycle. Even when the water is hot maybe not 140F it seems as though the heater does not energize. Does anyone know if this model has a control panel it seems that it's quite old.

I took the door off and no wiring problems were noticable. I guess I'm going to have to find the thermostat or the heater to test. Anyone know how to test the thermostat or heater on a SMU2042uc/14 model?

SMU's do not have that control unit, actually don't have any. Don't know your qualifications so am reluctant to go further but you probably have open lead to heater in wiring harness(can't see wires) you could run new wire but another one will go open soon. Junk it.

Well if that is an area that is exposed to moisture, and the wiring gets corroded... re-wire the bad wires and impregnate the harness with dielectric grease... unless it is an area that heats a lot causing the grease to run, or the wire ends are a real pain to reach. If I had one of these old school machines at hand, perhaps I would keep it until something major gives way.

Usually 1st wire to go open is L1-2nd is to heater,then circ motor- you can only go back so many times to rerun one wire at a time til customer gets pi$$ed even tho you warn them. Harness is NLA and wires where break occurs is in molded shield-to rerun entire harness would be too costly and not worth it-it could very well be a thermo,timer or heater but I always check power leaving timer down to verify harness.

True, minding the peace of the customer's mind, if the machine is known to be progressively degrading at an NLA part, I support euthanasia. The other way would be building a hassle of wiring to replace the bad harness in the first place, but that is known to be time consuming, and it still may not solve the problem. It's not our job to build appliance parts, unless we have a customer insisting on it if it is at all possible.
It's like doing $100 work on a machine worth $90 secondhand and functional... and finding out the problem wasn't solved. :shock:
This brings to me a memory from the good old halcyon days (doesn't history eventually become that?):?
A couple years ago I worked part time for a computer sales/service business. Sometimes it happened that the customer's computer was found to be beyond repair, or matching parts weren't reasonably priced if available. We would offer the policy that either we bill €50 for the service call, or the call is free plus a 10% discount of a new computer from our catalog if the deal is closed right then. If the customer wanted to think longer, the call was €50 and the 10% offer was up for two days.
Just one customer didn't like the catch, that EITHER a new OS licence was in the price OR the data from the old computer was transferred, no new OS. Separately acquired WinXP licence was €100 and the guy thought he had been ripped off... transfering old files and OS, which was considered basic service visit, would have been €50. He took that as the freebie in the deal and came back two days later demanding WinXP to be upgraded over the old OS, keeping old user data and applications, for €50.
Two words: NO DEAL.
