if the solenoid valve fails to close when 

the  power  is  disconnected,  it  needs 

cleaning:

1. 

isolate the water supplies and relieve 

the pressure by operating an outlet.

2.

  switch off the power and remove the 

nut and the washer which hold on the 

solenoid coil.

3.

  remove  the  solenoid  coil.  if  the 

solenoid  coil  is  'open  circuit'  then 

replace  it  (normal  impedance  is 

approximately 3 ohms (2022), and 8 

ohms (2028)).

4.

  remove  the  four  cap  screws  the 

washers,  the  cover  and  the  cover 

spring.

5.

  carefully  remove  the  diaphragm 

assembly.

6.

  inspect the rubber of the diaphragm. 

if the rubber is perished or damaged, 

then  replace  the  diaphragm 

assembly.

7.

  clean out any residue or debris from 

the body and make sure that all the 

holes are clear.

8.

  reassemble  the  components  in 

reverse order.
