Can you tell me what is wrong my dishwasher keeps coming up with a 20 fault and it beeps at me?

Debbie, December 2011

The 20 fault is not draining properly.
Check drain hose for kinks
Check the filters and clean if dirty
Check where the nose connects to the spigot under you sink. Remove the hose from the spigot and ensure that the spigot is clear.
If all these are OK the probability is the pump in the dishwasher.
