What is the cause of a heating problem in Bosch Exxcel Dishwasher

My Bosch SGS46e12gb/73 has developed a fault and won't finish a cycle (stays on 1 minute for ever). The water is cold - so I suspect it is a problem related to heating. There are various pages suggesting the relay on the PCB as the cause - although looking at mine I can't see any signs of burn out. Could the element have failed and how could I tell which is the problem ? We live in a hard water area if that helps.

SOURCE: Water not heating

probably not, believe it or not. If they actually designed a trace to fail under load, then they could not predict when it may happen. Yes, things get more load-some over long use and demand more current, but the pcb trace was probably not intentionally too small. Let's say it was designed too small. So at first startup it carries 9.5 Amps. The next factory unit draws 9.8 amps. the next unit, wait a minute, draws 10 amps and blew the trace before it got shipped. I think this under-design was a simple oversight, but one that should have demanded a product recall from Zanussi that would send a tech to every unit to install a pcb with a beefier trace. Email Zanussi and complain! Just curious...can you measure how wide is this pcb trace? It should be about 1/4 inch wide.

SOURCE: Dishwasher tablets not dissolving

It may just be the way you are loading the machine.  If the dishes are not allowing the the detergent door to open fully, the tablet sits in the dispenser until you open the dishwasher, letting the dispenser door open and the half dissolved tablet falls out!     Try being more careful how you load the machine or just chuck the tablet in the bottom of the machine instead of the dispenser!

Hi

First make sure that nothing is blocking the drain pump assembly located inside the lower front panel of the dishwasher. If the issue returns after its cleaned then try to reset the dishwasher control by pressing the HEATED DRY button and hold it for 15 seconds, if its still not resolved then it means that the control board has gone bad and should be replaced. Hope this helps...please post back for further assistance.

SOURCE: Bosch SGVE53E13GB Integrated dishwasher- cycles but won't finish

The heating element in the bottom of the unit may be burned out. With an ohm meter, check to see if there is any resistance with power removed and terminals of heating element exposed. If it measures about 1 or 2 ohms, it is okay. Anything more than about 200 ohms means there is likely a break in the element., If it is okay, then check the wiring to the heating element.

Wont finish cycle - keeps going with 1 minute still to go...


Hello there,

Long or endless wash cycle times indicate a fault in the water heating circuits. The water heater, NTC or the control module are the likely culprits. Some minor dis-assembly and testing will be required to determine the exact cause of the fault. Please can you answer the following simple questions to assist me in solving your problem:

1. Is the water heating?

Start a regular wash cycle, let it run for about 10-15 minutes, then open the door and check for steam or test the water temperature in the bottom of the washer by hand. The water should be hot, not luke-warm.

2. Do you have an RCD fitted in your consumer unit? (fuse/breaker box)
3. Do you have a Torx T20 screwdriver and a multimeter - these will be required for any testing and/or repair.

If your simply looking for a diagnosis and some idea of repair cost, the water heater and the control module are about £100 each to buy. The NTC is about £20 but this is less likely to be the cause of the problem. Labour charges will be extra. The control module can sometimes be repaired with a relatively simple re-soldering of the heater relay pin/s.

All of the above can be replaced on a DIY basis, but the water heater and NTC are best left to a professional.

If you need further assistance, please let me know the answers to the above questions.

Regards,
BElectric

Bosch exxcel multi programme ....programme gets to 1 min and then stays there. on the quick cycle on the auto cycle it gets to 60 min then returnsto 140min on the timer... thankyou


this is caused by incorrect water levels the appliance takes in too little water at final rinse and generates erro code 1 this is what you are getting it isnt 1 minute to go it will need the dishwasher equivalent of colonic irrigation several tubes will be full of fatty deposits,using the quick wash a lot will make this happen more often you will need an engineer to sort but shouldnt need any parts.

Make sure the drain pump is clear of any blockages and obstructions and that the drain hose wasn't kinked when you re-installed it.

My bosch exxcel dishwasher will not drain after wash cycle


That is because the water level switch activated by the floating sensor is stuck.

You probably need to have the water level switch replaced.
