Transcription

1 Fault/Alarm Code Cause/Problem Remedy/Solution ENER Emergency Button pushed in 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 Alm - A Alm - A1 Alm - A2 Alm - C (big C ) Machine not filling to required level in time allowed by processor board Machine not reaching set temperature for wash programme Or heating over and above the set temperature for the selected wash programme. (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 Alm - bal HS MACHINES ONLY Machine is detecting out of balanced load 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. Alm - c (small c ) Machine not cooling down correctly at end of wash programme (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.

2 Alm - prob 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. Alm - L Alm - E HS 4 Series Alm 013 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. Alm -SL Alm- star Machine going over the required water level. 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. 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 On HS *022 and upwards - The lock solenoid plunger has jammed inside the solenoid coil. Alm -fire Machine is detecting heating with heating being in off position (Electric) Heater contractor welded in, keeping heaters powered up. (Steam) Steam inlet valve badly letting-by. Alm - motr Or Alm - notr As it will be seen on the display Motor is tripping on overheat protector 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

3 vent inlets Alm - door 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. Alm - L5 During extraction cycle Machine not draining quickly enough Restriction in drain outlet. Drain valve not opening fully or sticking closed. End/bal End/red Check/bal Machine has ended cycle with load out of balance. 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 Out of balance microswitch permanently activated by sensor rod being out of position in mounting plate. Also see Alm - bal 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. Display sticking on Et.30 Et (full stop)30 On 4 series HS machines Only 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. Display sticking on count down at end of cycle. On 3 series HS machines Only 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.

4 Machine blows negative/neutral 16 amp.control fuse. On HS 4007 & 4012 machines only. Electrical overload in inverter unit. Restriction in drain outlet. Slow drainage of water causes inverter to overload safety fuses. Slow draining can be caused by oversoaping Inverter mains filter leaking to earth. Machine starts but Goes straight to End. or Alm - 00 Alm - 26 Alm - Com On HS 4 Series Only. Break in communication cable between processor board and inverter. Communication sub-board on inverter faulty. If fault occurs after changing inverter unit Check continuity between wiring of communication cable. Replace inverter unit. Check sink/source slide switch on inverter is in correct position. Machine starts O.K. Door locks/machine starts to fill but after a few seconds goes into Alm - A03, followed by cycle end. On HS 4 Series Only. Drive motor short circuit or shorting to earth. Drum bearings tight or seizing up Replace drive motor. Replace drum bearings and seals. Alm - A01 Alm - A02 Alm - A03 On HS 4 Series Only. Drive motor short circuit or shorting to earth. Short circuit or broken wiring between inverter output and drive motor. Drum bearings tight or seizing up Replace drive motor. Check/repair or replace wiring as necessary. Replace drum bearings and seals. Alm - A04 Alm - A05 On HS 4 Series Only Failure of the inverter to interpret Parameter frequency being downloaded from processor board Corrupted processor board EPROM. Alm - A06 Alm - A07 Alm - A08 D.C breaking being applied. Replace processor board

5 Alm - A11 Alm - A13 Inverter overheating. Restriction in drain outlet. Slow drainage of water causes inverter to overheat. Obstruction or insufficient cool air around inverter.(engineering bulletin No.353 shows how to clean inverter) Inverter cooling fan failure. Room temperature too high. Alm - A12 On HS 4 Series only Drive motor thermal protector tripped. Faulty drive motor. Drive motor ventilation fan(s) failed Drum bearings tight or seizing up. Heaters in drum buckled up restricting drum movement. Loose or worn drive belt(s) Room temperature too high. Alm - A16 Alm - A17 Alm - A19 Failure in the inverter to interpret the wash program. Drive motor overload. Corrupted processor board EPROM Restriction in drain outlet. Drum bearings tight or seizing up. Heaters in drum buckled up restricting drum movement. Loose connection in connections between motor and inverter. Alm - A20 Alm - A21 Corrupted data communication to inverter Fault in Earth connection. Imbalance between Earth and Neutral connections. High level of spikes or transients on phase line. Faulty inverter supply filter. Faulty inverter. Alm - A40 Inverter not configured. Use machine configuration program to reconfigure inverter. Faulty inverter, corrupted inverter memory. Alm - A41 Alm - A55 Corruption of inverter memory Use machine configuration program to reconfigure inverter. Fault in Earth connection. Imbalance between Earth and Neutral connections. High level of spikes or transients on phase line.(to overcome this problem a Communication circuit resistor is available, see Engineering

6 bulletin No.354en) Faulty inverter supply filter. Faulty inverter. Alm - A47 Overload in electrical supply Usually shows as a second alarm following Alm - A03 when drive motor faulty. Loose phase connection somewhere in electrical supply causing increase current load. Check inverter supply relay, due to faulty relay there maybe a voltage drop access relay contacts. Drum tumble action is erratic. No tumble action when machine loaded. But does not show any alarm condition On HS 4 Series only Drive belts badly worn or broken. Break down in inverter output circuits to motor Fit new belt set. Replace inverter unit. During heating cycle temperature display goes up step by step but then jumps to a much higher temperature reading On HS 4 Series only Fault in temperature sensor Replace temperature probe Err/CONF On HS 4 Series PM only Corruption of Processor Board EPROM Caused high level of electrical spikes in mains supply. Replace processor board EPROM. Err/EPrO On HS 4 Series PM only Corruption of Processor Board EPROM Caused high level of electrical spikes in mains supply. Replace processor board EPROM.
