Problem
Cause
Solution
1. Pump will not run
There are various potential causes for this problem. Please follow the steps below to diagnose and address the problem:
a. Is water supply on? If not, turn on water supply. If yes continue to step b.
b. Disconnect flush manifold wire harness from the pump stand and install the flush jumper that came with the pump stand.
c. Using the prime pump function of the controller, run one of the pumps.
d. If the pump runs, go to step e. If pump does not run, STOP troubleshooting, call Hydro Systems Technical Support for help.
e. Measure your water flow by following the steps below:
1) Turn off the incoming water supply.
2) Disconnect the brass water inlet fitting from the push-fit connector on the flow switch
3) Get an empty one gallon container.
4) Turn on water supply.
5) Capture the incoming water flow with the one gallon container and time how long it takes to fill the one gallon container.
6) If it fills in one minute or less, so your flow rate is at least 1 gallon per minute, proceed to step f.
7) If the incoming water flow is less than 1 gallon per minute, STOP and check your water supply.
(Water supply flow must be at least 1 gallon per minute for the Flush Manifold’s flow switch to activate.)
f. Reconnect the brass water inlet and supply hose to the push-fit connector on the Flush Manifold.
g. Reconnect the flush manifold wire harness to the pump stand.
h. Check that discharge hose to the washer is free of kinks.
i. Disconnect discharge hose at the washing machine inlet.
j. Aim discharge hose to floor drain and activate a pump using the prime feature.
If the pump runs, there is blockage at inlet fitting. If pump does not run proceed to step k.
k. Turn on a pump with the prime function and collect the fluid coming out the discharge hose in a one gallon container.
If the output is less 1 gallon per minute, proceed to step l. If the output is 1 gallon per minute or more, call Hydro Systems
Technical Support for assistance.
l. Activate a pump with the prime function and check voltage at the coil of the Flush Manifold solenoid valve.
If you measure 24 v and there is no flow at the manifold outlet, replace the solenoid valve.
If you do not measure 24 v on the coil of the solenoid with a pump active, call Hydro Systems Technical Support for help.
2. Water in chemical line,
between pump and flush
manifold
a. Chemical check valve
defective or clogged
Replace check valve.
3. Water drips/runs into the
washer at all times
a. Defective solenoid valve Rebuild or replace the solenoid valve.
4. Water leaks out of vent
check valve
a. Defective or clogged
vent check valve
A small amount of water may periodically leak from the vent check valve in normal operation. You can
attach a short length of tubing to the barb to capture the fluid. If you still see a significant amount of
water exiting the vent and tubing, the check valve has probably failed. Replace the vent check valve.
WARNING!
Under no circumstances should the flow switch be by-passed by jumping wires. The flow switch is a safety feature that if by-
passed will void the warranty of the Flush Manifold and Hydro Systems will not assume any responsibility for the mixing of chemicals in the manifold!
