Hi Mike
Thanks for your tip re Miele 638 not filling with water.
Surely solved our problem as well. There was a split in the supply hose, and it was dripping down inside the supply ducting from the 2 supply solenoid valves under the sink, therefore slowly filling the water catch tray with water. I replaced the hose, cleared the water and dried the area - AND BINGO, have thrown that washing up brush away. Thanks
