Troubleshooting
Fault
Possible cause
Remedy
Mixing controller cannot
draw in the chemical
metering medium
No dynamic pressure.
Pinch the outlet hose together. A dynamic pres-
sure is built up and a medium intake process is
initiated. The foot valve then ensures a continuous
intake through the inlet hose.
Insufficient water inlet
pressure.
Set the minimum pressure (2.0 bar).
Mixing controller stops
the intake of chemical
metering medium
Foot valve clogged or meter-
ing medium dried out.
Wash the foot valve in a hot water bath.
Measuring probe clogged
by dried metering medium.
Remove the measuring probe and inject hot
water. If there is still no intake, remove the mixing
controller and place in a hot water bath for
internal cleaning.
Mineral deposits at the
nozzle.
Remove all parts installed on the mixing
controller. Then clean the mixing controller in a
descaling bath.
Mixing controller contin
-
ues to draw in chemical
metering medium even
after closing the water
inlet valve
Surface of the chemical
metering medium is higher
than the lower end of the
outlet hose.
After use, store the container with the liquid to
be drawn in lower, or hang up the outlet hose
higher.
Valve malfunction
Push-button malfunction
Check whether the push-button can be moved
up and down easily and whether a clicking
noise is heard when the push-button is pressed /
released.
Remove the cover for inspection of the internal
parts and unscrew the solenoid housing. Pull off
the sheathing carefully so that the plunger cannot
fall out. Remove the spring and spacer. Check
whether soiling or damage is impairing the
function of the plunger. Trip a spring movement.
Inspect the diaphragm and ensure that the two
small holes (venting holes) in the diaphragm
pleat are free and enable closing of the valve.
Disposal
Do not throw the device away with normal household waste. Dispose of the device via an
approved waste disposal company or via your local authority waste disposal facility.
Observe the currently valid regulations. In case of doubt, contact your waste disposal
facility. Dispose of all packaging in an environmentally sound manner.
