was the steam boiler short cycling like that before you replaced the pressure safety?
Did you remove any other components to replace it? asking because I'm pretty sure i had to remove the water level sensor when replacing mine so that i could fit a wrench in there. if the water level sensor got pushed too far down, for example, the heating element could heat the smaller volume of water much faster....possibly causing the short cycles?? brainstorming outloud here. -mike On Thu, Jul 18, 2024, 11:54 AM Murray Roblin <[email protected]> wrote: > Hi Will. > I had a similar situation, addressed, partially, by replacing the > overpressure valve and the valve seat on the steam wand.
