What E12 actually means
The machine thinks there is too much water in the drum, so it has shut the cycle down and will normally pump out instead of washing.
Grundig machines monitor the water level with a pressure sensor. If that sensor reports the level has reached the anti-flood (aquastop) point, the control board stops the programme to avoid an overflow. The classic symptom is that the machine drains as soon as you switch it on and the programme won't start at all.
What usually causes it
- A genuine overfill / faulty water inlet valve letting water in continuously
- Faulty or blocked pressure (water level) sensor giving a false high reading
- Pressure hose to the sensor kinked, split or full of water
- Loose or unseated wiring plug between the level sensor and the control board
- Control board fault
What you can safely check yourself
Work through these in order. Anything beyond this — panels off, testing parts, anything to do with the wiring — is an engineer's job, and not one to attempt with the machine plugged in.
- Turn the machine off at the wall for a minute, then switch back on and try a short programme.
- Turn off the water supply tap and see whether the machine still fills or keeps draining \u2014 useful information for the engineer.
- Check the drain hose is not kinked, and that its end is not pushed too far down a standpipe.
- Clean the pump filter at the front of the machine so any water in the drum can drain properly.
When to call someone
This one usually needs an engineer once you have tried the checks above. We cover Nottinghamshire, Derbyshire and Leicestershire, and it's £66 including VAT for an engineer to come out and diagnose it — £84 in total if it's repaired on the visit with no parts needed. Any parts needed are quoted on site before we fit them — you decide. Every repair carries a 90-day workmanship guarantee.
Outside our area? The explanation above still stands — take it to a local engineer and tell them the code. Knowing it saves them time and you money.
