Ok so i return to the dishwasher to find the "check water" light lit. Open up and contents are washed to a point, however full with water in the bottom.
So - manually emptied bottom of unit and power reset, to get it to start from scratch. Also removed water hose from rear, checked for obstructions in the filter (which was fine) and also confirmed water getting to the unit at the usual pressure and with no obstructions.
Removed side panel and seeing no real much or gunk at all in the matrix, so decided to leave well alone (i'm an electronic engineer and have learnt that if it ain't broke, don't fix it....)
Decided to go for a short rinse cycle to see what was happening with the Matrix. So I re-connected my empty machine and off it went. Filled great. Washed great. Didn't empty - a few relay sounding clicks from the front panel, however it was all finished and the water sat in there. No "check water" light at this time. So, knowing that when you select a cycle the first thing it should do is empty, i did exactly this.
No empty though - it waited, waited, tried to fill... and "check Water" and the machine stopped.
Anyone any clues as to where to continue now? Could this possible be the "impeller jug", or the pump packed up - if someone could tell me exactly where the pump is located i'm sure i could stick a meter across the windings to see if there's anything amiss there!
Many thanks for any pointers
