weil mclain gv gold lockout problems
I have a 15 y.o. weil mclain gv gold gas boiler which is driving me nuts. It locks out frequently especially on cold nights (in New England). Repair men have replaced the control unit twice to no advantage. One thing I have recently noticed (but it may not be new since I am not very observant) is that there is little or no water draining out the drain hose. I wonder whether rust may be clogging the drain at the boiler housing. I can snake a wire up about 20" and feel nothing unusual. Nor is there increased drainage. I can see that the pressure switch is closing. The controller lights go through the normal sequence but it fails to fire often and then locks out. Turning it off for a minute and then restarting will usually get it working for minutes or hours then it locks out again. I have replaced the igniter and can see a glow through the little spy window so I think It works. My temporary solution is to splice a timer into the power line and have it shut off for 15 minutes every few hours. I would very much appreciate any ideas about what the problem is. It cannot be trusted to work through the night on a cold night and has been that way for years.
