Posted Mon Dec 2, 2013, 6:55pm Subject: Problems with beloved Quickmill Andreja Premium. HELP!
Several problems showed up today all appearing at the same time so clearly linkedů
First of all, I ran several descales yesterday. It was pretty dirty and since the machine was purchased used, I wasn't sure when/if it was ever done in the pastů maybe this triggered my current problems??? I have had the machine for several months and it's been working well so it didn't come to me with these issues.
First, I noticed that there was no pressure on boiler gauge. Then tried taps - no steam or water from the hot water tap, however, water seems to run normally through the group. I noticed that the pump to fill the boiler had not turned on in a while so I triggered the machine to manually fill the boiler by removing wire from auto-fill sensor.
Let it heat up for 8-10 minutes. Still no pressure on boiler gauge or steam/ hot water.
The on/off switch doesn't seem to be turning off either. I can't say for certain that this happened alongside all the other issues because I normally run the machine on a timer so don't usually touch the on/off switch at all. Last time I used it though, it worked fine.
I appreciate any help/advice you have for me. TIA, Marty

This may sound stupid, but is the water out of the grouphead hot? When you said you let it hear up for 8-10 minutes, it should have produced hot water somewhere - grouphead, steam wand, and/or water tap. If not, you probably tripped the thermal protection during the re-fill of your boiler after rinsing out your descale solution? A low water volume during heating would have tripped it. A simple press of the reset switch might be all that is needed.
This has nothing to do with not being able to turn the machine off. You got me there.

Water out of the group head is hot. Boiler heats up but I am getting no pressure showing on boiler pressure gauge and still no steam or hot water. After descaling I ran a few shots and several more today before the machine started acting up.
I can hear the sound of the element heating the water in the boiler and it seems like it is continuously heating. After about 20 minutes I can actually hear boiling/bubbling in the boiler but still no steam or pressure showing. I am wondering if there is something wrong with the overpressure valve? I think it's still open maybe? I didn't hear it close and usually I can hear a little sound when it closes.
I was hoping this would be an easy fix with the reset button (which I did press just in case) but it looks like I may be going without my latte in the morning. :-(

Thank you so much for the link. After reading through it, it sounded EXACTLY like what I was dealing with so I went straight to pulling the heating element and took a look. Sure enough it was burnt out. You've saved me a ton of troubleshooting headaches and possibly some unnecessary repairs. Cheers! Marty

Glad it worked out, but sorry it wasn't a more simple fix. One note on descaling for when you do it down the road; to prevent this from happening, unhook the terminals to the heating element until the boiler is full. Sadly, this piece of advice is rarely mentioned as a safety precaution in "Descaling How-To" threads.
One last bit of advice, if you don't mind. Before descaling, remove your mushroom to look for scale before you go through the hassle. Here's a good link to the procedure. Good softened water will really prolong the time between descaling, so though you might think it's time, scale (or lack of it) on the mushroom will tell you whether or not it is necessary.

Heated descaling solution works more effectively and faster than doing it cold. if descaling solution, properly mixed, eats through a heating element, odds are that it was about to happen anyway and the descaling exposed the bad area of the element sooner than later.
Common sense must prevail, and knowledge of the individual machine is important. The key factor here is to not drain the boiler or allow the water level to drop below the heating element when it is energized. Descaling more often with a weaker solution, using water that limits or eliminates scaling, and flushing the boiler to replace mineral laden water are also ways to increase a heating element's useful life.
The Inanely Long Water FAQ along with the Aquarium Pharmaceuticals GH+KH test kit are a good start in terms of developing a regime of what to do and how often.
