This dishwasher fills for about 20 seconds then emptys.
The programme then needs to be reset and started again but starts to empty again after about 20 seconds.
The pressure chamber and switch both appear ok.
The second light in from left flashes continuosly.
I know led 2 relates to fill problem , but a down to earth heater can cause this too , meg out heater ,there pigs for throwing up false error codes when heater is u/s
