Hot water tank Low Water sensor

[stampedecarwash]

Hello in our Coleman Hanna super saver the low water sensor inside the hot water tank sends false signal to the LW relay (so the green light is on) and as the system thinks the tank is empty it stops the pumps. Do you know where can I buy that sensor to replace?

Coleman sells them and they are not too expensive-maybe $20-25. I think Kleen rite also sells something that would work. In the meantime you can jump the switch off (i guess you've figured that out by now)

I always replace the high and low sensors at same time. I get mine form KR it’s a cheap enough part not to worry that he other will go out soon. I’ve actually “fixed” one of these as the issue was the metal ball bearing simply needed gluing back in place

thanks Greg actually could you show me how to bypass the switch?

Chaz, I dont have a high sensor, do you use coleman hanna as well? I dont even see a place for it (Thinking maybe someone removed it before), a picture would be nice.

I’ve got markvii gt 700. It has two identical switches turned in opposite directions. K/R part number
KR Part #: LLS100. Assuming your switch and functionality are similar....it’s as simple as wire nutting the two wires together so as to by pass the switch. BUT......get the switch replaced really soon cause if the tank really does go low, you will burn out the water heater!
