Zanussi Making Knocking Noise
Hi,
I have a Zanussi washing machine which is about 5-6 years old and it has stopped working. I am a student living alone and have very little disposable income so i have try and fix it myself! After searching through washing machine forums, i cannot find other faults which are identical to mine. Please could someone help me diagnose the problem?
My washing machine is a Zanussi Jetsystem iz12 and the problem is as follows:
When doing a normal wash cycle, everytime the drum does a full rotation it makes a knocking noise. When the drum spins faster, the noise gets louder and obviously more frequent due to the amount of rotations the drum is doing. With 20 minutes to go, during the rinse cycle, the machine begins to beep and an E20 error comes up. I can get past this by pressing pause and skipping to the spin cycle. Although skipping the cycle does enables me to spin the washing, it is extremely noisy!! Also when i skip to the spin cycle, it seems as though the washing hasn't been rinsed properly and there are signs of washing powder on some of the clothes.
If anyone can give me some advice on thisw then i can search for the problem online and attempt to fix it.
Thank you in advance.
Ryan

This thread was marked as solved. Here's a summary of the problem and the fix, generated from the discussion below.
Zanussi Jetsystem iz12 knocking on every drum rotation with E20 during rinse
- The problem
- A Zanussi Jetsystem iz12, around 5-6 years old, developed a knocking noise once per full drum rotation during wash, becoming louder and more frequent at higher spin speed. With about 20 minutes remaining, during rinse, it beeps and shows E20. The user could skip to spin, but the machine remained very noisy and clothes appeared poorly rinsed with traces of detergent left on them.
- Likely cause
- The accepted reply suggests two faults are likely. The knocking noise points to possible drum bearing wear. The E20 and poor rinsing point to a pump/drain problem, most likely restricted drainage rather than total pump failure, because the machine would still spin and was not reported as left full of water.
- What fixed it
- Recommended action was to check the pump filter for blockages and follow the forum troubleshooting for a washing machine not emptying. The noise was also considered consistent with failing drum bearings. No confirmed repair or final fix was posted, so the exact fault combination was not proven.
- Checks to try
- Observed knocking once per full drum rotation
- Noise became worse on faster spin
- E20 appeared during rinse
- Machine could still be advanced to spin
- Clothes showed signs of incomplete rinsing/detergent residue
- Pump filter should be checked for obstructions
Safety: Further diagnosis should be carried out by a suitably qualified appliance engineer.

It sounds in a bad way, maybe the drum bearings are going? E20 on Zanussi washing machines implicates a pump problem, which if you are finding the laundry hasn't been rinsed properly could mean the water isn't being pumped out fast enough. If the pump wasn't working at all you wouldn't get a spin and would have washer full of water so it must be pumping out the water, just not all of it. Make sure the pump filter has been checked for obstructions. Also check the troubleshooting link at the top of each page in this forum for the section covering washing machine not emptying.
