I'm having some trouble with my 3-way valve, replaced fairly recently by all accounts. I'm sure you'll recognise everything.
I have very restricted space here.
How does the case unit split away from the mechanical valve?
And what position should it be in to best disconnect. Does the power need to be on or off?
I want to see if I can see some misalignment or micro-switch failure.
The valve is sometimes sticking in what I think is the HW position once the HW is satisfied and ignoring the CH call for heat.
Sometime a light tap to the plastic case will with get it moving again, other times it is a pita to coax into movement - the far side of the case feels hot as if one solenoid/relay/resistor/motor has been trying. Attempting to move the small black lever manually seems fruitless.
I can see the middle black lever at the front (pic1) and feel the rounded black piece at the back (pic2) but squeezing these isn't releasing anything for me.
If I can't release it, or can't fix it, what is the best way to leave the heating so at least we don't freeze - can I lock off the unit with the lowest (moving) lever?
