Ek d5 problems

MrSir · March 17, 2018

Last weekend I started having issues with my pump. It didn't start when I booted my PC. I used a variable power source to check if my psu was the problem. It still didn't work. After that, I overvolted it. It started to run at about 20 volts, after which I quickly turned the voltage back down (regular is 12). It ran fine for two days, then it didn't start again. After some shaking of my case it worked again. That's how it went throughout the week, until yesterday it wouldn't start without overvolting. Today I drained my system, took my pump apart and it looked just fine. When I put my system back together it ran just fine again. This evening I tried booting again. It failed. Does anyone have an idea what the problem could be?

Pump is an ek x-res 140 d5 which is about 3-4 months old.

My only sort of plausible theory is that the cable could be bad, doesn't explain why it works when overvolted, but it's the best I got.

The pump should work at any voltage from between 8-24V given enough amperage from your variable power supply, note it requires around 25W. I would contact EKWB to see about getting that replaced it shouldn't have a starting issue if the correct amperage and voltage are supplied.
