My problem is the opposite of Tim's. My burner will not shut off automatically. the burner fires with the gun open or shut. Sunday the hot water did not work, replaced the hi-limit switch, still no hot water. Monday I had my service man work on the PW. He replaced the micro-switch in the ressure switch , burner fired. Did a chinese Tuesday nite,the burner fired constantly. blew the end off my hose going from the PW to the hose reel.yesterday I
replaced the hose and the hi-limit switch and the micro-switch in the pressure switch mounted in the head of the pump. I did see moisture in the pressure switch housing, and the plunger that shuts off the micro-switch does operate. Still the burner won't shut off. The new hose now is leaking through the crimp-on fitting, not around the fitting, throught the fitting it self. This thing is a bomb waiting to blow. I cancelled last nites work and hood cleaning work for the rest of the week, till I get this fixed and the machine is safe to use. This is a Delco RK 27 (Elite)w/General TS 2021. At 245 hours I replaced the transformer, at 375 hours I replaced the hi-limit switch. I don't know how many hours now, but I have replced 3 hi-limit switches, 1 transformer, 2 micro-switches in the pressure switch, 1 pressure switch in less less than 500 hours. I have taken the pump apart and replaced the ceramic plungers 3 times. Isn't this an excessive amount of repair to the machine? Of course, it seems to go down when I have out of town work scheduled.
