H150i Elite LCD AIO pump not running correctly

[HippyHoppety]

Hello

I've just installed the H150i Elite LCD AIO. Unfortunately, the pump doesn't run and iCue only shows the commander core. (The display also doesn't work and shows a red exclamation mark. The fans/RGB on the other hand work fine.)

I've already tried the following troubleshooting steps:

1. "Cold Start" (shut down, reboval of power, etc.)
2. Checking all cable connections (USB header, CPU fan, power, and the 20-pin connector to the commander core)
3. Updating/Checking if the commander core is up to date.

Thank you for your help in advance!

Are you sure the pump is not running?  Not just the CUE “pump fail warning” (which can be false) but a steady and continuous cpu temp climb on power on. The best way to test this is to stop in the BIOS and watch the cpu temp. You’ll get one shot at it before it becomes trapped in the 70-90c range. If that is what you see and you’ve checked the SATA to Commander Core and the wide power/data cable from Com Core to pump, then this is likely a bad unit and there’s no troubleshooting to do. Straight to replacement.

 

If the pump is working when in the bios (cpu temp normal) but then either shuts off on CUE load (rare) or gives the false pump fail, no lcd detect in cue, or red (!), then there is some hope. All you can do is keep trying on the shutdown, PSU off, physically disconnect and reconnect the wide power cable on the Com Core and pop the top off the lcd and reseat. Make sure you disconnect the top and wide power cable. They are very finicky.

Thank you very much for your answer. The CPU hits temps above 70 degrees (Celsius) right after start up. iCue doesn‘t show the AIO at all. It only display the commander core.

I hope it‘s not another broken unit. It should have been the replacement unit for another one 😂

Thank you anyway!

This means the pump is not starting at power on. Two possibilities: 1) Dead pump. Not user fixable. Return or RMA. 2) Bad cable or connection between Commander Core and pump. The pump gets its power through the Commander Core. Do the power cycle one more time, make sure that wide cable is deeply connected with the white stripe lined up to the corresponding mark on the Commander Core. 
 

If you’ve checked this repeatedly and it still won’t start the pump at power on, then proceed like it’s a dead pump. The connectivity and communication between lcd top and CUE can be difficult, but it’s not suppose to cause the pump not to run. There’s no way to turn it off, so it has to be mechanical or electrical failure. Most mechanical failures are very noisy at the moment it happens and give a noisy warning leading up to the critical event.

Thank you very much. I'll check it one last time.
