XO 4 & XO FLEX TROUBLE SHOOTING GUIDE

Version 3.30

Valves & contacts connections in the "Basic configuration" and "suction cleaning".

Failure description

Reason

Solution

Overflow (mixing cup)

The liquid sensor pins are misaligned

or defective S11T

Measures the water treatment fluid in

the reservoir

Check that the pins do not touch the
edges of the mixing cup or are short-

circuited.
Consult the chapter

“Liquid Sensor PCB, AP-869” on
page 56
Replace Liquid Sensor PCB AP-869.

The water supply valve V39 is

defective

Verify that the connectors are

properly inserted.
Measure the voltage at the coil

connectors 24VDC
Measure the coil resistance (≈100Ω).

Change if defective UC-584.
Disassemble and clean the valve at

the piston.
Change the plunger seat gasket

(MR-150).
