I need help with troubleshooting some equipment. Thanks in advance for any help. I don’t have access to my equipment right now so i can find random old pics to see machine but can’t take new pics to be precise. Warning: long text ahead as issue hard to describe with my limited experience and knowledge of terminology.
It’s a steamer. Whitco 2525 PEO. I meant to do an “upgrade” to help use less antifreeze when winterizing between every job. It seems this is how i broke it. There is a tank with a float valve where a garden hose attaches to the top side and water falls in the tank. There is a hole on the bottom of the tank where the water is being pumped. I thought it would be a good idea to hook up the garden hose directly to the thread at the bottom of the tank where it is pumped. I thought there’s a reason the thread is there so it must be ok. It seems this applied excessive water pressure at a part in the water inlet side somewhere. It worked once, then since that time, the burner never would turn on. The water pump works fine. I tried all kinds of things and put it back the way it was before (water falling in tank through top side with float valve, instead of garden hose screwed to bottom thread in tank). It didn’t work and i put it back with the hose threaded in the bottom again. Then accidently the garden hose was kinked when i turned the switch to the burner and the burner came on for the first time since. I repeated the experience a few times. I cannot get the burner to turn on when water falls in the tank by gravity (original setup). I cannot get burner to turn on when hose threaded to bottom and water flowing directly. I can only get burner to turn on when hose is threaded to bottom of tank AND hose is kinked and no water gets through. I researched a lot online and it seems i’m getting near the solution learning about pressure switch/ flow switch/ vacuum switch/ flow actuator?
Any and all help very much appreciated.
Also i thought this was to prime the diesel line so i played a lot with it when trying to get the burner to work. Now i think it looks like a vacuum switch? See vacuum switch pic from google.
