Help with Bosch Classixx Maxx

Hi

I have a problem with a Bosch Classixx ( SG855C02GB ). It started mid cycle the check water supply warning light coming on. I then checked bottom of dishwasher and all clean. Reset machine and started new programme then impeller starts running and then after about 1 minute light comes back on. I then ended up removing pipe from back checking filter and flow no problems found. Re connected and the all works fine for 2 weeks.

Began fault finding again cleaned out bottom of dishwasher tipped water in and turned on, all pumped away very quickly, but then carries on trying to pump and light then Check Water light comes back on again. Tried turning dial to reset position and tried again on all programmes but same light coming on impeller spinning immediately then after 1 min lights comes back on while impellar carries on spinning.

Ended up taking hose of back again and reconnecting, turned back on and no impellar running for 30 seconds then it starts spinning and pumping as if it is all fixed after 10 minutes into programmes light comes back on again.

Any suggestions and help would be greatly appreciated. Thanks in advance.
