I'm a little puzzled what my problem could be. I have a Bock (Wayne
Head) oil fired water heater. A month ago I began to have problems.
The fire was pulsating. I changed out the pump (12 years old anyway),
the safety controlsm, photo cell, transformer, electrodes and changed
every filter. Every few days the controls with break the circuit and I
have to press the red button to restart the heater. The burner never
looses prime and always re-starts immediately. I even tightened all
the fittings to fix an air leaks. The only parts I haven't changed is
the motor and aquastat.
Does anyone have any clues? I'm reluctant to call anyone because it's
a real crap shoot to find someone that can diagnose an intermitten
problem like this. Thanks in advance.
