Today i fitted a pcb and an diverter vavle to a optimax he 38 c when i come to switch it on and fire it up f37 is on the display. f37 is system pressure to low but it was at 1.5 bar any suggestions anyone
Yeah thats what i thought gonna replace the sensor if its thatblocked low water pressure sensor?????
how do i test ittest it first like! save a few bob!
thanksjust a switch C NO & NC you would get continuity between C NO if there is 1bar in the boiler, but if there is 1 bar in the blr an continuity between C NC then its fooked
this is a standsrd Low wtr pressure switch.
