Posted Sun Jun 30, 2013, 3:50pm Subject: Astra Mega II problems with the boiler
I'm helping someone who is starting a coffee drive thru with a machine; an Astra Mega II She told me that after the machine was on for about 2 hours the Pressure gauge needle was buried, all the way up and the pressure release valve leaking water
a couple of days later I came to look at it. I turned it on, I saw no leaks, the machine ran fine and it and according to her it stayed good for at least 7 hours
then in the morning there was water leaked onto the floor and the pressure gauge was again peaked out
I came turned it on and couldn't get it to act up again. I was there for 2.5 hours. If the inlet valve was stuck open I would have seen that while I was there. The same with the depth sensor. As I checked the pressurestat I noticed it's connections were cruddy. I Filed down the connections with emery board and ordered a new pressurestat
it made it through the night without leaking, she turned the machine off the next day for other reasons.
When the part came in I came and changed the pressurestat - everything seemed to work fine and it stayed fine for at least 5 or 6 hours.
The next day there was water all over the counter and floor and leaking from the boiler. I came and repaired a small leak from my work, but it wouldn't explain the water on the floor. It seemed to work fine as I was there for about 3 hours.
next day - water was all over counter and floor again and the circuit breaker was tripped and when they plugged it in there was a big spark from the machine she thinks the spark was from the pressure stat .
Any ideas where to go from here? What would cause the machine to work fine for several hours and then start leaking? and would it be moisture in the electrical that caused the circuit breaker to pop?
