Zanussi ZDP7207PZ Not Pumping Water to Container

Hi folks,

Having some trouble diagnosing what might be the issue here. Initial symptom was that a few minutes into a cycle, I would get the empty tank light. The tank was completely empty. After a little research, I found out it’s typically down to the drain pump failing or being blocked so here’s what I’ve tested:

• Took drain pump out and made sure no blockage – all good here.
• Took float switch out and made sure it was travelling up and down freely – all good here.
• Tested continuity in the float switch to check it was OK – all good here.
• Tested that there was power getting to the float switch – all good here.
• Tested continuity in the pump – all good here.
• Tested that there was power getting to the pump – nothing. Tried a few different ways here (with float switch activated/deactivated, in/out of a cycle etc).
• Tested continuity from the block connector from the PCB to the pump – all good here.

So I don’t know a lot about how these work (e.g. maybe the pump only runs at particular times, but it looks to me like the pump just isn’t getting any power. Am I testing the right things here? Anything I haven’t considered or that I should be testing?
