Can you post the model number please.
Also when and how did you get the e27 error code?
Its a Zanussi Jetsystem 1200 XC6.
The error code E27 came up last week, but I opened up the filter and it was clear. ER20 came up today when it was about 8 mins from the end of the whole wash cycle.
Ok there isn't actually a error code E27 on these. There is a E20 which is a draining issue.
What you need to do is check the drain hose and were it drains to. If it goes under a sink then remove the hose and check it isn't blocked up under there.
If that's all fine and the filter is clear and the hose going from the drum to the pump is all clear then its proberly a faulty drain pump here.
Replace the pump and this should cure the fault for you.
If you need anymore info just get back to me.
