Mini 17-18-19 and boiler shut off issue
Posted: Thu Aug 01, 2019 1:05 pm
I've been reading the posts for some time trying to resolve these issues and will set out my observations below.
S1 Mini
Boiler shut down.
I take it that this is the result of inadequate filling and the shut down prevents overheating. It happens every time on start up. If I reset the boiler it runs for 1 minute and shuts down again. We steam modest amounts of milk and it has continued to allow steaming but may require a couple of resets. I've opened the case and note there is an air bubble in the clear hose between the solenoid and the boiler. The bubble doesn't seem to move, suggesting to me that there is a flow blockage of some kind somewhere in the line. I'm wondering what the best way to test the line is. Do I simply take apart all the tubing and make sure they are clear? We use a softener and after 9 years use there are almost no deposits on the lines I have removed. Could this be the solenoid and how can I test it? At first glance it seems to be working as there is a loud click when the power is turned on. Is it possible that the pump output is degraded and that is causing the issue? It vibrates and makes the usual sounds. This problem has existed for a couple of months.

This just started and has prompted me to open the machine as the water dosing is too high and the lights flash when I try to make 2 cups. I gather that his is flowmeter related, but upon removing the flowmeter it has no buildup on the connections or on the screen. I tried to remove the lid but it is firmly stuck on even though the screws have been removed. I'm a bit concerned about breaking the lid. When I blow through it I can hear it rotating inside and air goes through it easily. Could this be a problem with the "brains" attached to the lid? I understand it might also be a line blockage and have checked the line between the group boiler and the flow meter and found no blockage or buildup. What's the best way to check the lines before the flowmeter?
Any advice would be appreciated. I'm new to Vivaldi repair with only basic electrical knowledge - I can use a meter to test resistance etc.
Thanks for any assistance.
