Domestic water system switches off within
a short time
Check whether the switch-off pressure
displayed on the pressure gauge agrees with
the calculated value
Switch-off pressure does not agree
with the system parameters
Set switch-off pressure (routine 1)
Check gas supply pressure of the diaphragm vessel (see Table1: approx. pE - 0.2..0.5 bar or pE - 10%)
Gas supply pressure of the diaphragm vessel
agrees with the system parameters
Domestic water system switches on or
off less than once a minute
Installation and operating instructions Wilo domestic water systems Hxx

Mount the pressure switch cover
Domestic water system does not switch off
Set switch-off pressure (routine 1)
Establish electrical power supply and check
the settings using the values displayed on
the pressure gauge
Switch-off pressure does not agree with the
system parameters
Gas supply pressure of the diaphragm vessel does
not agree with the system parameters
Set gas supply pressure (routine 2)
Domestic water system switches on or
off more often than once a minute
Increase difference between
switch-on pressure and switch-off
pressure (routine 3)
Establish electrical power supply and check
the settings using the values displayed on
