[30] High pressure switch failure

Re-connect

If connection between pressure

switch and connecting board is

good

If the system pressure meets the

condition that pressure switch

shuts off

Make pressure switch

close, measure if terminal

is conductive by multimeter

If the system is clogged

Make pressure switch terminal

on connecting board in short

circuit, check if failure exists

still

Replace pressure switch and

measure again

Replace pressure switch

Check the piping system

Replace connecting board
