Just had the same and fixed it with the advice above.


Pop the black panels off, stick a towel in, soak up water, quick test to check no E4 comes up, put the kettle on, take the credit off the wife, feet up.

The hardest part was putting the integrated kitchen back together.

REMOVE MAINS POWER COMPLETELY, then remove the plastic covers from base of machine and sponge out the bottom catch tray

    I'll also add - I've just diagnosed on my machine that the polystyrene float that trips the microswitch to cause this error, can get stuck to the drip tray, rendering it useless. This will allow too much water to accumulate in the tray. Result - water level too great and spills into the shield stuck onto the bottom of the motor, and in my case seems to be the cause of the fuse-board tripping when the motor tries to start (I'll piost back if fitting new motor cures the problem). I now know where to get a new pump/motor at a fraction of the cost of the usual suppliers.....

    I have "fixed" this problem - don't allow the flat base of the styrene float to rest flat on the base of the drip tray, stick something, anything (no more than 2 mm thick) to the catch tray under the float.

    Yes, the new pump/motor assembly has cured the board tripping, so the motor must have been damaged by water getting into it, although it doesn't appear to have signs of damage to the windings. Only time will tell but all is well now, and the cost of replacement justified giving it a go.

    If anyone wants to know where I got the new motor at a third of the cost of a "genuine" replacement, click on my dame and "Ask Me".

Baumatic BDW45. Keeps tripping the electric out when on a wash cycle and leaves water in the bottom. If I put it on a rince only it works fine. Help

your tub is running out of balance could be due to your counter balance weight in the bottom or excessive load shift sometime you can try rocking the tub by hand to re center it or you may have to turn it on it's side to see if the retaining pins are locked on the tub or the balance weight is broken

Error code e4

This might be a re-badged generic dishwasher - on my Baumatic E4 error caused by floatswitch in bottom catch tray. Some (supposedly small amount) water collects here and should evaporate naturally. If it accumulates, float rises and stops machine.


try to find a way into the machine base catch-tray to sponge it out - on the Baumatic there are two large black plastic plugs on the front of the machine base that can be forcibly flipped out.

failing that, take machine out and tip it up to get rid of water

I need to reset my dishwasher but don't know how!!

If it's any help then here is the link to the user manual (when you download it it applies to bdw13 as well even though it is labelled for the bdw14) Best I could come up with is to try page 19 at the bottom of the "dishwasher doesn't run" section - there are two different types of reset which may do the job. Hope this helps :)
