Hi, has anyone experienced this issue before?
There is lost motion in the pivoting switch mechanism that’s activated by the DP flow switch and therefore it sticks on. You have to tap the black box to release the switch when you try to call for hot water
The actual DP switch itself is working fine, the needle raises and lowers as it should. It’s purely the rocker switch housing that the needle goes into that is at fault here.
Can anyone recommend a quality replacement switch housing as this problem has existed since installation.
It’s a Ravenheat CSI 120T boiler
