5.3 Solenoid Cleaning
1. Turn off the Dosetronic and solenoid power supplies at the
wall. Refer to system overview for their location.
2. Carefully remove the solenoid valve from the grommet in the
tank (empty your tank first!)
3. Undo the top ring nut on the valve. This should be hand tight,
but it may be necessary to use a pair of pliers if it is too tight,
as shown in Figure 1.
4. Take the black coil off the solenoid, as shown in Figure 2.
5. Undo the two screws on the solenoid as shown in Figure 3.
6. Carefully disassemble the solenoid valve as shown in
Figure
4.
Be very careful not to lose the spring between the
piston and the cylinder. Remove the diaphragm gently – do
not use any sharp tools.
7. Clean the diaphram (Figure 5) using Jif or dishwashing
detergent and a toothbrush if necessary. Check the
diaphragm carefully for holes / splits or any other
damage.
