Error Message Explanation - Maytag MXS20 Programming Manual

EXTERNAL COMMUNICATION PROBLEMS
The washer communicates with the PC (TraceTech SW) via the RS485 line. If the external communication is not working, check the
connection between the PC and washer. Check also if you have selected the correct washer communication address.
FAILURE 2: DRAIN FAILURE
Failure 2 occurs when the electronic timer detects that the water is not drained after 3 minutes in a Drain or Spin Sequence.
The Failure Message is displayed at the end of the cycle.
DIAGNOSE:
1. Check the drain tube of the washer.
2. Check the drain valve.
3. Check the wiring:
When the drain valve is switched Off, the drain valve should
be open. (normal open)
FAILURE 3: SAFETY SWITCH ACTIVATED
Failure 3 occurs occurs when the safety switch gets activated at revolutions lower than the distribution level, i.e. in the wash, rinse, soak
sequence, etc. but not during the extract sequence. The error is generated when the safety switch is switched more than 10 times (for a short
period of time) or for a period over 20 seconds.
DIAGNOSE:
1. Check if the safety switch is broken.
(Make sure shipping braces are removed)
2. Check the position of the safety switch.
3. Check the wiring, the contact of the safety switch
is normally closed. Check connector pins for loose
connections.
FAILURE 4: LOAD IS NOT CORRECTLY DISTRIBUTED IN THE STAGE WHEN WASHER STARTS SPINNING SEQUENCE
Failure 4 occurs if the load is incorrectly distributed in the washer when it switches from distribution revolutions into high revolutions or during
the spinning sequence at low revolutions.
If the safety switch is activated, the washer first attempts five times to redistribute the load in the drum and carry out the spinning sequence.
If the safety switch gets activated 5 times, the spinning sequence will be skipped. This function will protect the washer against overload and
ensures the normal lifetime of the washer.
DIAGNOSE:
1. Check the position of the safety switch.
2. If this failure occurs often.
3. Check the wiring if there is no bad connection.
The safety switch is an NC contact.
4. Check whether the washer is overloaded.
5. Check the springs.

Error Messages Explanation
If the drain tube is blocked: repair the drain tube.
If the drain valve is defective: replace the drain valve.
If the wiring is damaged: repair the wiring.
If the safety switch is broken: replace the safety switch.
If the safety switch is not correctly mounted: install the safety
switch properly.
If the wiring is damaged: repair the wiring.
If the safety switch is not correctly mounted, install the safety
switch properly.
Use a fully loaded drum. A completely filled drum produces
less imbalance than a drum that is only 1/3 filled.
If there is a bad connection, repair the wiring.
Do not exceed the specified washer capacity.
Replace if necessary.
