Question about Dishwashers
Possible, heating element is defective or other electrical problem and is washing with cold water.
the drying process is casued by the heat generated, this causes the water on the plates to evaporate and collect at the bottom.
if the water is not being heated this can not happen.
try setting your next wash to the hotest setting and see if the problem is the same
this will indicate so.
I hope this was useful.

The cause is one of 3 possibles.
1. The heating element is faulty.
2. The water sensor on the heating circuit is clogged with debris
3. The switching relay on control board is faulty
Lay dishwasher on its side and remove bottom panel. Will need care to remove water spill connections from inside cover and put to one side.
1. Heater element can be identified as a sausage-shaped assembly with the characteristic ceramic insulators on the ends of the element. remove cable connections and test with an ohm meter.Resistance of around 48 ohms says it is probably OK
2. Follow the heater cable connections a few cms and one is connected to the water sensor. disconnect and remove it. By blowing gently down where the hose normally fits on the sensor you should here the switch click on and off. If not, clean out all the debris, wash in hot water and try again. Test with ohm meter which should show the switch open and closing
If all seems OK then replace bottom cover making sure water spill connectors are replaced first.
3. To replace the switching relay requires basic soldering skills. From the front of the machine, pull down lid and undo all the screws (6) holding the control panel in place. to the right is the control board.
To the right of the board is a large black component some 30mm x 20mm x 10mm. This needs to be replaced by a similar component. In my case, I could not find a unit which would fit on the control board so I bought an alternative and soldered wire tails and tucked it in alongside the control board. Remember to use heavy cables on the mains switching side as these take the heater current.
