Zanussi [E10] fault codewhat it means and how to fix it

E10 sits in the E1 family, which in this scheme means a water supply problem: the machine called for water and did not get enough of it in time. It appears as E11 or C1 on some models, and as a single beep and a single flash on machines without a display. The manufacturer publishes something here that most do not, which is a specification rather than a vague instruction.

Every Zanussi manual read for this page puts the minimum supply pressure at 0.5 bar; the maximum is printed as 8 bar in the 2014 Lindo100 and ZWF 01483 manuals and as 10 bar in later ones such as the ZWF142E3PW, so check your own manual for the top figure.

It is the bottom figure that matters here. It gives you a number to work against instead of guessing whether the flow "seems alright", and it explains a category of fault that has nothing to do with the machine at all — a property on a weak or shared mains, or one where a pressure-reducing valve has been set low, can sit below 0.5 bar and produce this code on a machine in perfect condition. The manual’s own advice on that is to contact your local water authority for the pressure information. It is worth knowing before you pay somebody to tell you the appliance is fine.

1. 1

   On a machine with no display, count the pulses first. One beep and one flash puts you on a fill fault; two would send you to draining instead.

2. 2

   Check the tap is fully open, turning it right off and right on again rather than judging by the handle position.

3. 3

   Turn the tap off, unscrew the fill hose at the machine end into a bucket, and rinse the gauze filter in the connector until light passes through it.

   Tap off before you unscrew, and a towel underneath. The hose holds more water than it looks like it should.
4. 4

   Test the supply while the hose is off, using the manufacturer’s own method: fill a bucket from the open tap and time it. You should get about ten litres in a minute. Anything much slower is the supply rather than the machine, and no amount of appliance repair will fix it.

5. 5

   Straighten the hose along its whole run, reconnect it by hand and make sure it runs straight, as the manufacturer’s article puts it, then run a short cycle while watching both ends for weeping.

6. 6

   If the code is still there with the tap open and the filters clean, do the manufacturer’s reset: unplug the machine, wait at least thirty seconds, plug it back in and restart the cycle. They say this can clear a temporary system error. If it returns after that, or no water is entering the machine at all, the article’s own escalation is to contact an authorised service centre, because a faulty inlet valve or sensor is a professional repair.
