When the washing machine is set to Wash Plus at 60 degrees this programme normally takes approx 2hrs 15 minutes,but suddenly after about 10 minutes into the programme the timing has “jumped 1 hr and reads 1hr 15 minutes remaining.The machine heats up ok.We called in the Bosch Engineer as we have insurance.The engineer spent some time trying to diagnose the problem and finally decided to replace the main printed circuit board[larger one of the two circuit boards] and the Heater Thermostat,after which he ran the machine through a diagnostic test,though we were not asked to put washing into the machine to try it.The Engineer said that the Machine was functioning correctly but when my wife tried to use it later the machine jumped an hour again !.Can anyone advise on what the problem might be?The Machine is nearly 5 years old now,and the Insurance plan is due to expire in July so its in our interest to get Bosch to fix it correctly..Any help appreciated..Michael NB My wife switches the Macine off at the Mains after use,so the computer must be rebooted the next time its switched on.

Are we talking a ‘Cottons’ wash plus wash or an ‘Easy Care’ wash plus cycle? The former would be approx 2hrs the latter 1+ hrs. Bearing in mind the machine automatically adjusts the time based on load, fill time, inlet water temperature, water hardness etc etc. So often the time can be shortened considerably from its ‘default’ timing as a result.
Are the clothes washed OK after these shortened times?
Re: Bosch WAE 24364GB 1200 spin Programme fault?
I understand that the machine uses fuzzy logic and as you say this can reduce the programme duration accordingly.However we have had the Machine for 5 years and the programme duration shortening hasn’t happened before like this ie 1hr lost in 2hrs?..the programme in question is the 2hr+ Cotton wash plus set at 60 degrees The machine is not washing correctly as the washing is very creased on completion.Sorry for delay in replying Martin Cheers Michael
Re: Bosch WAE 24364GB 1200 spin Programme fault?
OK so my only suspicion would be an earth leak on the main motor. In fact any earth leakage from any component (motor, heater) can affect the fuzzy logic of the circuit board. You say the engineer checked everything before deciding on replacing the stat and board, I wonder if that included checking for earth leakage? An obvious check for an engineer to do and likely as not he may well have done so. Nonetheless that is my only suspicion at this stage as to the likely reason the programme times and poor tangled washing are apparent.
I wonder also how well it takes to drain out? Almost 5 yrs use and the drain system will be getting pretty sludged up by now. Bosch are notoriously bad for that. Grey sludge ingress blocking the grey flexi drain hose and black rubber tub/sump hose. Also the bleed air vent from the drain hose to the dispenser easily gets blocked. Shared drain spigots under the sink prone to getting blocked. Has the drain system been thoroughly checked?

Martin..I dont know whether he checked for an earth leak from the motor all I know is that he didnt pull out the machine,from under the worksurface he just unclipped the control panel.He has been back and replaced another circuit board[smaller one of the two]and told my wife to try all the programmes?The machine has had very light use as its “a second machine” we have a more modern beko machine as well and my wife tends to use this most times and only uses both when shee is washing sheets etc She is quite fasidious with both and makes sure the drawers are clean,as well as the sump plugs on both machines We also live in a soft water area so scaling up isnt a problem.The drains were checked.

In that case he couldn’t know what state the heater or motor is in. It is a fundamental necessity to carry out an insulation test and to do that the machine has to be pulled out!

So where do I go from here as our Domestic and General Policy ends on 30th June,what do you suggest? Michael

Call them again, get them back explaining that so far their repair attempts have failed. That your policy covers having it repaired conclusively. Perhaps ask why the didn’t pull the machine out and inspect it thoroughly before proclaiming they had fixed it?
Re: Bosch WAE 24364GB 1200 spin Programme fault?
Thanks Martin,I have spoken to Customer Service at Domestic and General and asked them to log my concerns about the two previous Bosch attempts to fix my washing machine,and the fact that that the machine wasn’t pulled out from under the work surface and inspected thoroughly ie to include checking the motor and heater for earth leakage.They have suggested that before we get Bosch involved again, my wife runs the Wash Plus programme at 60 degrees .We have agreed to do this and get back to them with our findings.I must say that Domestic and General have been more helpful than Bosch! Michael..PS I will come back to the forum to report on the outcome.
Re: Bosch WAE 24364GB 1200 spin Programme fault?
Martin..The Bosch Engineer is booked to visit us on Friday 6th June,as he hasnt been able to fix the problem we have with our machine.You mentioned in your last reply that he should have checked the motor for earth leakage as an earth leak on either the motor or heater could affect the fuzzy logic chip.We live in a modern house which is 20 years old and has a modern RCB circuit breaker.Whilst using this Bosch Machine the RCB has never tripped,does this mean that there could still be an earth leakage,but not enough to trip the RCB?Iff a faultis found would this mean that either/or both the Heater and Motor would have to be replaced? Sorry for asking again,but need to have my facts right before the Engineer calls!Reply Appreciated and thanks for your help Michael
Re: Bosch WAE 24364GB 1200 spin Programme fault?
It’s fundamental that the earth potential should be tested by an engineer. Also the supply to the machine needs inspecting as a matter of course. To do that the machine has to be pulled out. Who knows what lurks behind? Only a slight earth leak can cause problems. Too slight in fact for an MCB/RCD to trip especially if the earth return is compromised. Heaters and motors are easily tested, easily replaced. Let’s hope a more detailed examination takes place on Friday. 😀
