Cause/Problem Emergency Button pushed in
Alm - A Alm - A1 Alm - A2
Machine not filling to required level in time allowed by processor board
Alm - C (big ‘C’)
Machine not reaching set temperature for wash programme Or heating over and above the set temperature for the selected wash programme.
Alm - bal
HS MACHINES ONLY Machine is detecting out of balanced load
Alm - c (small ‘c’)
Machine not cooling down correctly at end of wash programme
Remedy/Solution Red mushroom button on front of machine has been pushed in. To clear - rotate red knob anticlockwise, you will feel knob pop out. Also press START/STOP key to reset
(1)In coming water pressure too low. (2)Water inlet valve filters blocked (3) Faulty water inlet valve. Faulty water valve coil? (4) Drain valve letting-by (5) A split in the water level control tube causing the processor board not to be able to read the level of water in the drum. (Electric heating) (1) One or more heating element blown. (2) Wiring to heaters burnt out. (Usually heater terminals but can be on heater contactor connections or on mains connections coming in) (Steam Heating) (1) Steam strainer blocked (2) Steam inlet valve letting-by
The machine will try 3 times to redistribute the load, before stopping on Alm - bal. Problem can be caused by load balling-up (Duvet) Or load too small for machine, not being able to distribute evenly around drum during extraction.
(1) Cold water inlet pressures too low (2) Cold inlet valve filter blocked. (3) On 4 series machines, heater contactors stick in during heating cycle forcing machine into cool-down to correct the overheating situation, which ends in an Alm - ‘c’. Problem is usually due to processor board fault. (4) Problem can be caused by hot water inlet pressure being higher than the cold.

ALARM CODES/FAULTS FOR HS 3 series and HS 4 series also LS 3** With SM and PM processor boards. Alm - prob
Alm - L Alm - E
Water temperature prob faulty
Temperature prob-sensor is open circuit or shorting to outer drum. (1) check electrical connection onto prob-sensor. (2) In most cases the problem is due to the soap dispenser hose leaking which causes water to run down the outer drum and wet the prob-sensor, so shorting it out. (3) In most cases Alm -prob faults will require the prob-sensor to be replaced.
Alarm - L usually occurs at the end of the cycle, telling the operator that the machine has not drain correctly
(1) Drain outlet blocked (water left in machine at end of cycle) (2) Water level control bellows (air bell) blocked with soap ‘n’ scale. (no water left in machine at end of cycle) (3) This fault is common on 3 series processor boards, requiring two adjustment pots on the board to be re-set This repair procedure can be found in the series 3 manual.
Machine going over the required water level.
Water inlet valve not closing off completely causing machine to overfill. On LS and HS *007/*012 machines The thermal-actuator is blown or open circuit

Machine door lock has not activated in the time allowed by processor board. Fault may also be reported as machine flashes pre-star, pre-star, pre-star then goes into alarm.
Machine is detecting heating with heating being in off position
Motor is tripping on overheat protector
On HS *022 and upwards - The lock solenoid plunger has jammed inside the solenoid coil. (Electric) Heater contractor welded in, keeping heaters powered up. (Steam) Steam inlet valve badly letting-by.
On LS machines only there is a Miniature Circuit breaker located inside the mains connection box. This is accessible by removing the mains connection cover at the rear of the machine and resetting the circuit breaker. On Both LS and HS machines this fault is normally due to drainage problems. Also check for fluff build-up on motor

Check/bal
Door lock has failed during cycle
Thermal-Actuator has failed during cycle. Hinge microswitch or wiring to switch is failing, usually occurs during extraction. Fault in Processor board.
On HS 4 Series only.
Restriction in drain outlet.
Machine not draining quickly enough
Drain valve not opening fully or sticking closed.
Machine has ended cycle with load out of balance.
Out of balance microswitch permanently activated by sensor rod being out of position in mounting plate. Also see Alm - bal
On 4 series HS machines Only Machine has detected an out of balance load, and has reduced the final extraction speed
This means that the processor has not detected any movement in the out of balance sensor for something like 500 loads
Load too small for machine, not being able to distribute evenly around drum during extraction, which reduces the final extraction speed. And displays End/red to show this is the outcome. (1) Out of balance sensor rod broken or not inside holding plate. (2) damaged microswitch. (3) damaged wiring to microswitch. To clear display, remove the front panel, Start machine and advance it into final extraction, during extraction push the sensor rod up twice only to operate the out of balance microswitch.
On 4 series HS machines Only Display sticking on Et.30 Et (full stop)30
Machine not draining correctly
Restriction in drain outlet. Drain valve not opening. Problem should result in Alm - L or Alm - E, if not processor board faulty.
On 3 series HS machines Only Display sticking on count down at end of cycle.
V4/200906
Door lock blocking bar sticking. Partial blockage in water level control air bellows.
Door lock blocking bar sticking in slide causing door release microswitch not to clear. Remove and clean water level bellows.
