Hi everyone, my espresso machine is acting odd and I am pursuing help in
1. identifying a trimmer pot
2. determining if the problem is the trimmer pot
I have an espresso machine that changes the pressure in the boiler frequently when I turn it off then on again. The pictures below shows the board and a zoom on the board to help identify the trimmer pot. That pot is how adjustments are made to the boiler pressure; however, symptoms are as follows: the bar changes significantly just turning the machine off for the night and tuning on again the next day. When I adjust the trimmer, I sometimes barley turn the pot and it changes the bar an enormous amount and other times I turn the pot a lot and it barley changes the pressure. This makes adjusting tedious and time consuming. This adjustment should not have to be made, much, if at all, yet I usually have to do it multiple times each week. Sometimes it adjusts quickly and I am up and running in five minutes. Other times, it takes 20 minutes because of the crazy variations I am getting. I am assuming this is an issue of the trimmer pot going bad? I took these photos to get your help in identifying what type of pot to purchase to repair it. I added the other information to get your opinion as to whether or not I am going in the right direction. FYI, the circuit board is 10 years old. It is a Rancilio Epocha E1 Espresso Machine. I have a local electronics guy who offered to solder the new pot on, if that is the problem. A new board is over $800 and the only option the manufacturer offers. They where not able to tell me what pot to get, so I am appealing here for help in an attempt to repair the board. Thank you, Michael - Penguin Yell Coffee.
