Re: Bosch SGS43C02GB/35 Classix control unit Programming

Thanks Dave,
I’ll take a look with a magnifying glass but for now I’m just letting it run for 20 minutes then throwing in a tablet as it starts its main wash cycle. Not sure it is worth investing in a new programming unit. Might do though as I am very pleased with the performance of the dishwasher and most people tell me that newer units are not as good

Re: Bosch SGS43C02GB/35 Classix control unit Programming

Dave
Thanks, I did open up the controller unit, it all looks ok. Contacts are good, no signs of burn out on the PCBs etc. I’ll try searching the net further for instructions as I’m wondering whether it was indeed programmed correctly after the recall. It was quite a while ago and I cant remember whether the dispenser door problem was pre existing that fix or not. I don’t think the test done by the service engineer would have tested the dispenser door, as I recall it only took a few minutes.

If anyone else does have the instructions to set up a new programmer for this model it would be very much appreciated.

Re: Bosch SGS43C02GB/35 Classix control unit Programming

Dave,
Yes the dishwasher was subject to the repair action and the timer was replaced. I’m now trying to check if the new timer was programmed correctly

The FD number is 8309 and here is the information from the programmer if it helps

Re: Bosch SGS43C02GB/35 Classix control unit Programming

Dave,
The issue is the tablet dispenser door not working. It has been replaced so I suspect the controller. It stopped working sometime ago, maybe before the controller was replaced under the fire recall.

I just wanted to eliminate any mis programming that may have occurred before I purchase a new control unit. Not sure about the ENR number, is that from the control unit itself?

Re: Bosch Dishwasher TroubleShooting

Martin, I thought so too which is why I replaced the dispenser door. Didn’t help. I did apply 240 volts to the red solenoid. It does work, it moves quite slowly but does open the door, seems to be expanding wax inside I think which explains the slow movement. I don’t think it is getting 240 volts during the wash cycle. I also checked the wiring from the control unit to the solenoid. So I think it is either the control unit or wiring connection on to the control unit unless it could be the programming of the control unit.

Do you have instructions to programme the control unit?

Re: Bosch Dishwasher TroubleShooting

i know this is an old post but sounds like I might have a similar mis-configuration issue after the recall and replacement of the timer.
Could such a mis-configuration cause the tablet door not to open during the wash cycle. I have replaced the door but still no joy.
The dishwasher is usable by manually putting the tablet in after the rinse cycle (20 mins).

What is the sequence to programme the timer?
If this isn’t the issue, anyone got any other ideas?
I know the door is working separately as I have tested it and the wiring from the programmer to the door is good

Any help gratefully received

Re: Bosch SGS43C02GB not filling

So the new inlet solenoid is in and is working a treat, thanks Dave, your diagnosis was spot on.

While I have the front panel off I’m still trying to get the tablet door to work properly
I replaced the door a while ago but it didn’t resolve the problem
If I apply 240 volts to the terminals little red plunger in the tablet door it does slowly and successfully open the door. However putting a meter on the wiring to it during a cycle I don’t think it ever receives 240 volts from the main programmer. I have checked continuity in the wiring, no problems there so it must either be the connection to the main programmer or the programmer itself. Anyone got any thoughts on that?
Is that a programmable function on the controller. To be honest I can’t remember when it stopped working, could it have been something that was missed when the new programmer was installed after the recall

Any help gratefully received

Re: Bosch SGS43C02GB not filling

so the inlet solenoid is getting 240 volts after the drain pump stops and having removed it, it is open circuit. New one ordered.

So Dave looks like your diagnosis was correct, many thanks for your help

Re: Bosch SGS43C02GB not filling

Many thanks Dave, I’ll give that a try this morning. I did see that the part is available on here for just over £20. So if the coil is dead I’ll try that.

Any thoughts on the tablet dispenser not working?

I assume that must be activated at the beginning of the main hot wash cycle. I was thinking of putting a test lamp on the circuit to see if it is energised during the wash cycle. On that note I was trying to ascertain exactly what the cycle entails, couldn’t find it on the internet but assume it is something like
fill, cold rinse, about 30 mins
fill, hot wash main cycle, assume it is here that the tablet door should open, lasts around an hour?
fill, hot rinse and then drying, not sure how long that should last

Do you have any details?
Many thanks once again for your time and help

Re: Bosch SGS43C02GB not filling

btw it is an SGS43C)2GB/35 if that helps and it seemed to drain successfully, I assume that was the rinse cycle and then no fill.

for information it has had the main control board replaced under the recall about two years ago

Only other information I can give you is that the tablet dispenser stopping working about 6 months ago. I replaced the unit but still no joy so I suspect it isn’t being triggered from the main PCB

[martin1956]

Re: Bosch SGS43C02GB not filling

Dave, yes and after a while the drain pump stops and then no action.
I have filled it manually using a jug and it is now off running a cycle
I’m waiting to see if it drains at the end

Re: Whirlpool SCW1012UG

Having read a repair manual for a whirlpool duet found on the web the first part of the cycle is a child safety programme which precedes every programme :- door locks, 3 seconds of water fill, 5 seconds of door open, then door lock and programme starts. I don’t get the door open phase, so I’m guessing that either half the solenoid on the door lock is blown or the ccu is not providing voltage to it. The later seems more likely since the coils tested good for continuity and I could only see voltage on 1 of the 3 pins on the door lock actuator. Anyone know what may be the problem?
