Re: Baumatic BDW13 error code E4.
READ ALL BEFORE YOU ATTEMPT THIS SO IT DOES NOT GO WRONG
What I did is
put a towel in the salt despenser to drain all the water out (or as near as damn it)
then switch it on and wait till it gurgles
then put a small cup of water down the gurgling drain
leave it switched on for a few seconds then turn it off
turn it back on and problem solved.
it took about 10 min and saved £75
