Hi i wondered if anyone could give me some advice about my dishwasher. It is running through the cycles ok, but doesnt seem to be heating up. At the end of the wash the dishes are cold and no heat is felt when i open the door. The 4th light is flashing rapidly (think its the drying light). The dishes dont feel or look clean like they did before. There is soap suds in the bottom of the machine too. In the manual it doesnt mention about the 4th light flashing…. Cheers
