Hi, welcome to Just answer
Please tell me its complete model number
starts with E nr
and how old is it ?
srs5co2gb/09 6years old
The loud knocking sound that you hear...is it coming from top or bottom of the unit ?
and you have already tried to clean everything from the base of the unit ?
Does it drain fine ?
So it fills fine and then the red water light comes on and you hear the sound
and you have removed the lower base and cleaned everything from inside ...there is no leak and no water in the base ?
Yes that's it ,but the only time everything works ok is on rinse programme and also the quick wash. It drains fine on these programmes but on the full wash is when red light comes on and knocking sound is heard.
There is no leak. but water is in the base
as the water is in the base it seems that the anti flood device has been activated
can you pull the unit out
and the lay it on its back by around 45 degrees
so that the water comes off
once the water is removed from the base it should work...
also clean the upper spray arm
let me know how this goes
Is that it
also check to make sure that nothing is jamming the drain pump
