Functional Problems
Electrically isolate the machine before any maintenance
Maintenance should only be performed by qualified personnel
Always check the indicator lights on the machine before calling maintenance staff, as simple remedies may
work.
Problem Possible Causes / Resolution
Machine is not clean internally after use
•
Lack of water or a failure to circulate within the machine.
Check that the main water solenoid valve is operating.
• Make sure that the main isolating valve is open. Is the
water isolator service valve in the ‘Open’ position?
• Check that the pump is working.
Underside of lid has a deposit after use
• Check for foreign matter in the gap of the vent in the centre
of the lid.
•
If this is blocked, remove the vent, clean it and replace it.
• The jet gap must be the same around its circumference.
• If the problem is with the pump you will require an
exchange unit for this part.
Lid seal is leaking
•
Check that the lid seal sits centrally on the lid gasket.
Adjust and rectify, before making any adjustments to the
latch mechanism.
•
Remove any scum that has accumulated around the
lid/hopper seal area.
Unable to open lid
•
Power failure. A solenoid on the latch mechanism locks the
lid. The lid cannot be opened until:
1. The power is restored.
2. The Interlock Latch is released manually.
Once open check the operation of the latch and replace as
necessary
Unable to close lid
•
Foreign object present. Investigate and remove.
Internal water leakage
•
The Pulveriser or Pump mechanical seal is leaking
Fit a new mechanical seal in the main assembly, or if
the pump is leaking, exchange this for a new part.
• The plumbing is leaking.
Investigate where the leakage originates and rectify
the problem.
• Damaged Hopper Seal.
Replace the Hopper seal, ensuring that the new seal
fits correctly.
