CORRECTIVE ACTION
35. WASHER FILL LEVEL IS TOO HIGH. (Above 11 inches [280 mm])
Step 1.
Step 2.
Step 3.
Step 4.
Check for obstruction in air trap (located between drain valves), clean as required.
Check for water in air trap tube (this indicates a leak in air tube). Repair or replace
tubing.
Refer to malfunction 34 and perform steps 2 and 3.
Check for malfunctioning water inlet valve. Operate manual override on control
solenoids and observe valve operation. Insure inlet valve air supply is adequate (60 to
80 psi [4 H to 552 kPa]).
a.
If air supply is adequate (malfunction 32 above), replace the defective valve.
Refer to paragraph 2-22.

Check that air supply pressure is correct (60 to 80 psi [414 to 552 kPa]).
c.
Replace or repair drain valve.
37. WASHER DOES NOT FILL WITH COLD/HOT WATER (AUTOMATIC OR MANUAL
MODE).
Step 1.
Check for blown fuse in controller assembly.

Check for too low or too high air pressure. Normal is 60 to 80 psi (414 to 552 kPa).
a.
If air pressure is incorrect, adjust air system for proper pressure. Refer to
paragraph 2-26.
b.
If air pressure is correct, proceed to next step.
