11:9 DRUM OVERFILLED
This error code is shown if the mechanical level sensor connected to input DRUM OVERFILLED detects a high level
(used primary in W&D machines)
Possible causes:
This error code can be caused by for example water inlets not closing correctly, faulty level switch, blocked level
hose, drops of water in the level hose, foam in drum or level hose, etc.
Recommended actions:
1. Check in the service program that all the water valves are working correctly.
2. Check that the level switch is working correctly. Switch is normally closed.
3. Blow through the level hose and check that it is not blocked and does not contain any water or foam.
11:10 MAX TIME DRAIN
This error code will only occur in drain or extraction modules.
Error is activated if the level system has not indicated "empty drum" within a certain time (approximately 3 min). This
time may vary depending on the size of the machine.
Maximum allowed drain time is defined in Config. 2 parameter MAX DRAIN TIME.
Level for empty drum is defined in Config. 2 parameter LEVEL EMPTY, (may not be changed unless agreed with fac-
tory since it affects other functionality as well).
Recommended actions:
1. Check drain for dirt.
2. Blow through the level hose and check that it is not blocked and does not contain any water.
3. Check in the service program that the level control is working correctly.
4. Check for detergent overdosing/remains of foam.
5. Make sure the installation of the drain system follows the installation manual for the machine.
6. Monitor a program by using Process viewer in ELS Common Service Tool.
11:12 NO LEVEL SENSOR
This error code is activated if the CPU detects that there is no electronic level sensor connected.
It can also be caused by a broken cable to the sensor or a broken sensor.
11:16 TIMEOUT HEATING
This error code will be shown if total heating time in a program is longer than a Maximum allowed heating time, typi-
cally 2h 30 min.
Maximum allowed heating time is defined in Config. 2 parameter HEATING TIMEOUT.
Compared to Error code 11:8 - NO HEATING, this error code measures the maximum allowed heating time.
Possible causes:
Could occur if machine heats properly (min. temperature increase during heating is OK), but there is a drain leakage
causing repeated fillings.
11:17 DOOR LOCK
This error code is shown if the input for DOOR LOCKED is active at program start, i.e. the door is locked although the
control system has not requested locking.
Recommended actions:
1. Check door lock functionality in service program, by activating door lock and then by checking inputs.
2. Check DLCU status in service mode for more information on possible causes.
3. If DLCU is in error mode, wait five minuts for automatic reset or manually reset the DLCU in service mode.
11:27 LEVEL OFFSET
This error code is shown at program start if the level sensor indicates a level above what the control system CPU can
compensate for. If high level is indicated a attempt is made to first drain the machine.
Maximum allowed level offset is defined in Config. 2 parameter MAX LEV. ZERO OFFS.
The drain time before error code is triggered is defined in Config. 2 parameter MAX DRAIN TIME START.
Possible causes:
