Matachana MAT LD50 / MAT LD60
Matachana · Model MAT LD50 / MAT LD60
The MAT LD50 and MAT LD60 washers thermodisinfectors, with external dimensions of 600 mm x 850 mm x 605 mm, have a washing capacity up to 8 DIN 1/1 baskets in 4 levels. Wide range of complementary elements adapted to the needs of each installation Control panel with LED display Door locking system during wash cycles and automatic unlock at the end of the cycle MAT LD60 incorporates forced drying module with hot air and HEPA H14 filter Thermal disinfection and 54O measurement Integrated water softener and steam condenser 2 peristaltic dosing pumps and 2 water connections.
Key tips
- ·A failed biological indicator means the entire load is not sterile - no exceptions, regardless of how the cycle printout looks.
- ·Door gasket wear is the most common real cause of a failed vacuum/pressure test - check it before deeper diagnostics.
- ·Water quality directly affects steam-cycle validity - don't ignore scale or mineral buildup.
Typical Failure Modes
Compiled for this model from its own documentation and established engineering knowledge for this equipment class - not from a verified service record. Confirm against the manufacturer's service manual.
Cycle fault / abort
HighSymptoms: Cycle stops with a fault code, load not processed, door locked.
Root cause: Water fill / drain fault, temperature not reached, a dosing-pump fault, or a spray-arm blockage.
Poor cleaning / spray-arm blockage
MediumSymptoms: Instruments come out soiled, spray arms not rotating.
Root cause: Clogged spray-arm nozzles, a blocked filter / strainer, or low water pressure.
Chemistry dosing fault
MediumSymptoms: Detergent / neutraliser / lubricant not dosed, dosing-pump alarm.
Root cause: Empty chemistry container, an air-locked or worn dosing pump, or a level sensor.
Thermal-disinfection temperature not reached
HighSymptoms: A0 / disinfection temperature not achieved.
Root cause: Heater element, temperature sensor, or steam supply.
Door / seal fault
MediumSymptoms: Leaks during the cycle, door will not lock / unlock.
Root cause: Worn door gasket or a door-lock solenoid.

- ·Door gasket / seal inspection
- ·Steam trap and drain strainer cleaning
- ·Annual full PM and pressure-vessel certification
Troubleshooting Approach
A starting sequence for this model, compiled from its documentation and engineering knowledge for this equipment class. Follow the manufacturer's service documentation for the actual procedure.
Symptom: Cycle fault / abort
- Note the fault code and the phase it aborted in.
- Check the water fill and drain, and the chamber filter / strainer.
- Confirm the spray arms rotate freely and the nozzles are clear.
- Verify the heater reaches temperature and the sensor agrees with a reference.
- Follow the service manual for the specific code.
Symptom: Instruments still soiled
- Clear the spray-arm nozzles and check the arms spin.
- Clean the chamber filter / strainer.
- Confirm detergent is dosing.
- Check the water pressure and temperature.
- Run a soil / protein test on the next cycle.
