Got a Bosch Slimline Dishwasher ( Sorry dont have the model number to hand at the moment ) all of the stated wash times on the digital numerical display are double what they should be : i.e Quick wash 35c should be 32mins but shows 120 mins,
The machine fills, washes and heats, pumps out and the customer says that the appliance actually runs for the stated time !
Any ideas what this may be, I am thinking it may be the PCB ?
Thanks

I’m not…..the times are only approximate at the first time is the default. I suspect nowt wrong, just needs a service to make sure all is well anyway. 8)
Re: Bosch Slimline Diswasher
Sorry Martin, maybe I did not make myself clear, when I said that the customer says it runs for the stated time I meant that if she selects a Quick wash of 35c the time used to show 32mins. But now it shows 120 mins and actually takes 2 hours to complete this wash ????
I have read the manual and section that deals with program times and that states that the displayed times can vary depended on the usual things like incoming water pressure, heating time etc etc.
But two hours to do a quick was is not exactly quick is it ? and as the customer has had this machine four years the specifed 32mins is more or less the time that it takes to do this cycle.
Do you still think that nowt is wrong ???
Thanks 🙂
Re: Bosch Slimline Diswasher
I had a similar problem with a Bosch.
The control unit settings had been changed so the buttons being pressed didn’t relate to the washes selected.
Re: Bosch Slimline Diswasher
I had one of these about 6 months ago. Same display issue and not washing properly even though it ran for 2hours. It turned out that the relay on the board for the heater had gone so the temperature sensor couldn’t jog the program on.
As Martin quite rightly touched on, the control board remembers the timing from the previous wash and uses that as a starter and updates itself based on sensor readings during the cycle.
The board was duly replaced and the heater subsequently checked which worked but was pulling a lot of current so that went too. The heater was….not an easy job (polite version) as it’s in the sump at the base of the unit!Re: Bosch Slimline Diswasher

Ah now you have corrected your post then there surely is a problem needs attention. Such a shame we don’t know what the hell model it is so generalisation has to apply.
The heater needs testing, blockages in the water inlet matrix/pressure chamber. I guess too it has a turbidity sensor which could be crudded up giving false feed-back. Visual inspection of the module followed by the usual live test run.
HTH? 😀
Re: Bosch Slimline Diswasher
dry joints on heater relay on pcb are common, although not sure if it would cause this fault. sounds like the program selection maybe out of sink. when you fit a new module it has to be set to the correct model. if you could get your hands on the set up procedure it might be worth a try.
hope this helps!Re: Bosch Slimline Diswasher
Martin Said,

I will post the model later, as bad as the customers with no model number ah !. Anyway in the meatime thanks Martin, yes this model does have a turbidity Sensor as its at Logix xxx series. The heater is heating and checks out fine. What I did find is that both the spray arms were restricted, cleaned those out and the Qucik 35c wash now running at 33 mins and showing 33 mins instead of 112 mins ????
I am testing further this morning and will be back with the model.

Sorted then, twas the turbidity sensor just doing it’s job showing a flow problem after all.:D
Re: Bosch Slimline Diswasher
Model Number SRS56L08GB/18
There I got it, had another look at this earlier and the wash times shown before I cleaned the blocked spray arms was 55-65c Auto Wash = 199 mins
Short wash 35c = 120mins.The wash times now after cleaning show 55-65c Auto wash = 119 mins ?
and 35c = 33 mins.Do these wash time estimates sound correct for this model ?

Re: Bosch Slimline Diswasher
On test yeterday on the 55 65c wash the appliance gets down to 70 mins and then with the wash pump continually running it runs without refiling.
I have not take the DA chamber off and cleaned the water device with the float etc and see if that makes any difference.Sounds like a low water level prob on the rinse fill . Have you checked and cleaned the ribbed hose between the pressure chamber and sump ? There could be water being trapped in the pressure chamber after the initial wash/drain that is tricking the appliance into thinking it is already fulll of water. This wuld also account fot the long running times as it’s probably not heating up in the rinse cycle .
Re: Bosch Slimline Diswasher
Thanks, I have already had the ribbed hose of and that was clear, however since I had the DA chamber and float chamber off and cleaned that, I tried it today and it went passed the 70 mins ! I think that the blocked spray arms and gunge in the float chamber was causing the excessive program times.
