Hi Guys, Been reading, investigating and still stumped, going to call WLL tomorrow.
Machine is a B2 with gicar PID and matching temp sensor (recieved from WLL after original controller died years ago.) Its the PID with black border and blue text. Sister-in-law over, come home and reservoir is out of water, machine off (via reservoir weight switch.) Fill boiler and turn it on, get a weird flicker flashing on pid display, barely legible "1.05". I leave it on, steam pressure is fine but no brew temp. No leaks that I can see so probably emptied by drawing water from spigot. Anyway I check out the machine with multimeter and not seeing or measuring anything wrong except no power being sent to brew boiler relay (and boiler). Steam boiler working, pstat powered, 0.5ohm resistance at overtemp switches, etc. Brew boiler relay LED never blinks. I measured brew temp probe resistance at 60K Ohms at room temp. If I disconnect the brew temp probe pid correctly shows code A1 (at least that works). PID doesn't respond to key presses on startup - until the steam boiler is up to temp. Once steam boiler is at pressure the pid display stops blinking and I can enter the menu by cycling power, but still no worky. Measured power to the PID: I get 121V when steam boiler light is off but that drops to 112V when steam boiler is heating. When PID gets 112V its display flashes really quickly. At this point I'm expecting I'll need a new pid. Thinking problem with its conversion from 110V AC to DC. Has anyone successfully brought a PID back to life from this state? Thinking of taking it out, opening it up and looking for a problem, maybe I'll try reheating any solder points. Thanks!
