Grimac Mia Not holding Pressure once hot
Hi guys I've got a Grimac Mia that I've bought used a year ago its been wonderful the last year but a few days ago it broke
The issue is it heats up as usual and comes up to pressure cycles a few times then the element stops coming on and it loses pressure, even the boiler does not refill if I use some water from it
if I wait say 30 minutes after shutting it off and turn it on, it fills the boiler and heat up again cycles a few times and then the element stops coming on and it loses pressure
I tried to change the microswitch on the pressurestat, it made no difference , I even had the switch off the pressurestat and it did not turn on the element to try and rule out the piston part as faulty
I see it has a cubic ricerca mfc25g 220v in it and I did a bit of googling some one said something like the power supply on the board over heats
Does any one have experience in a issue like this
Thanks
