Bosch 1400 exxcel - cycles are taking over twice as long

So the cycles on my Bosch WM ( WDO2866GB/07 ) are taking much longer than they should...the rinse programme seems fine.

Im trying to work out if its the element / thermostat or the programme board...which is what several repair people have suggested

Its 10yrs old but don't want to replace unless I have to...I gather a new board means it not worth repairing but if it's the thermostat it is.

On the hottest wash the glass did not seem that hot but not sure if that proves anything or not. No error codes showing. I am in a hard water area.

Any thoughts or suggestions would be gratefully received...please

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.

Bosch WDO2866GB/07 wash cycles running far too long

The problem
A Bosch Exxcel 1400 WDO2866GB/07 washing machine was reported to take more than twice the normal time on wash cycles, while the rinse programme appeared normal. No error codes were shown. The door glass on the hottest wash did not seem very hot, and the machine is in a hard water area.
Likely cause
The strongest diagnosis in the discussion was a heating fault, most likely an open-circuit heating element or a heavily limescaled element reducing heating performance. A programme board fault was mentioned by others but was not supported by any testing in the thread.
What fixed it
No confirmed repair was documented. The accepted advice was that the machine needs inspection to determine whether the heater is open circuit, badly scaled, or whether another fault such as the control system is responsible. Given the lack of definitive testing in the thread, further diagnosis should be carried out by a suitably qualified appliance engineer.
Checks to try
  • Rinse programme reportedly worked normally
  • No error codes were displayed
  • Door glass on hottest wash did not seem very hot
  • Hard water area noted
  • Listen for excessive 'kettling' noise during wash as a possible sign of limescale on the element
Parts or tools mentioned
  • Heating element
  • Programme board

Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

Ironically it could be a heating element fault. With some washing machines if the heater goes open circuit it can produce an extra long wash time with no error code. Also, if the element was badly caked in limescale it could reduce its effectiveness to heat the water drastically. If you can hear the "kettling" sound a lot during wash that could be it. But it also could be any of the other things you mention. Unfortunately there's no way to test which it is without someone looking at it. To be honest, 10 years is pretty good these days.
