MediumRoastSteam I heard ECM was reputable, I’m beginning to regret buying this - two dud machines in a row, and the company doesn’t respond - but if I fix it myself, warranty is void. Thats a pretty raw deal for almost $2k USD.

In all honesty, your reseller should take more accountability and responsibility as the warranty is with them. The fact your reseller is unresponsive is far from ideal.

It’s quite unfortunate that you had two dud machines - and I understand how frustrate you might be as you have technically expected ECM to be more of a premium brand. However, to be fair to ECM, the pump having an intermittent fault is a very difficult one to spot in QC.

    MediumRoastSteam Agreed, the first machines bad OPV seems like it would’ve been easier to catch. If you and/or @DavecUK can watch the video in the dropbox link, please let me know your thoughts on the issue, and if the pump seems suspect.

      MetalDave @DavecUK I was able to get a video of it this morning, heres a dropbox link:

      I did get it to work eventually (and I had to download it), honestly it’s easier to put on YouTube as unlisted!

      The pump sounds a bit like it’s running against a blockage, but even then the sound is a bit quiet, definitely not running dry.

      Is water flooding out of the expansion valve tube leading back to the tank? If not then you should try a new pump. I should add a little water is quite normal.

      ECM won’t really get involved because your warranty is with the Retailer and they should resolve the problem.

      MetalDave - Now… That’s weird. That must be incredibly frustrating.

      When you activate the pump and there’s no pressure registering in either gauges… Is there water going back into the water tank (you can see water going back into the water tank towards the end of the video - but then the gauge was registering pressure).

        MediumRoastSteam @DavecUK It didn’t do it this morning, so I am not certain, but I do recall water coming back into the resevoir. I will check again when it recurrs.

          It depends how much, some at 9 bar is normal as it bypasses to maintain the pressure, gushing out with 2 bar isn’t.

            MetalDave None at 2 bar, steady at 9

            I really think it might be a faulty pump….video might help with the diagnosis, or for £17, get a, Ulka pump and fit it.

              MetalDave - maybe ask your retailer if they can send you a pump and ask them if they are happy for you to fit it - just trying not to void warranty etc.
