Hey guys… I’m at a loss here. I have a breville infuser (Bes840).
the issue is the program light will blink and beep and the only button that will function is the power button.
I originally took it apart and found when I unplugged one of the solenoids it started working fine, so naturally I purchased a new solenoid assembly and it worked great for a few days. After that the same problem occurred. If I mess with it enough turning it on and off I can get it to pull a shot, so I know the pump/water flow/power is working. The problem happens while it’s hot, if it’s unplugged for awhile then plugged in and turned on it the power will flash as normal until temperature reached and then the program will flash and all buttons become useless.
I also purchased a new pcb board from breville and installed that with no change to the symptoms. The steam and water function will work fine even with the issue.
ok here’s the really weird part, every now and then the machine will not turn on and I have to unplug/plug it back in a few times for it to power on. The odd part is even with it off the thermocoil is heating, everything is getting power including the solenoid valves!!!! The triac board had some white marks on it but it is testing fine per ohms on my multimeter.
the only thing I can think of is the power/program button pcb board may be bad and causing a short with the program button?
also when it will randomly work to pull a shot all of the buttons work normally.
thank you guys for any help you have. I love this little espresso maker and I’d hate to get rid of it.
