Probe type water level sensors

NShak

How do you go about cleaning the LWCO probe?
Here's my idea, but I'm no pro, just an average schmo homeowner:

1) Drain down boiler below the LWCO port.
2) Disconnect the system from the boiler.
3) Disassemble the LWCO to get to the probe.
4) Wash w/ warm water (no soap or detergents).

Does this sound reasonable.
Is this something that should be left to a pro.

As I've learned from Dan's book...
Know what you (homeowner) can do, and know when to keep your hands in your pockets and call a pro!

Probe type water level sensors

A friend is having trouble with his boiler overfilling. Based on the appearance of lack of maintenance, I am suspicious that the probe is falsely sensing low water and turning on the auto fill. When the level got too high last night, the boiler turned off. Does the probe unit also sense too high water levels and turn off the boiler?

I'd Check Grainger or McMaster Carr

lwco probe

no probe does not sense overfilled boiler whats happening is the hi water is getting into the pigtail and causing the pressuretrol to activate an soon as you drain the water down the pressuretrol bo longer senses pressure and boiler will run again

if the boiler hasnt been serviced in a long time the probe should be removed and cleaned most likely it has scale build up on it when reinstalling the probe go easy on the pipe dope leave 1st few theards uncovered

If it has scale build up on the probe, what is the best way to get that off? On a lot of things I would just scrape it off , but would that possibly be bad for the probe? Thanks again.
