TROUBLE-SHOOTING COMMON ISSUES
Pre-Service Check List
-
Check the appliance is plugged into a powerpoint and the switch is on.
Check the cable is not damaged.
Check to see if there is an isolator switch for the equipment and that it is also switched on.
Try plugging the appliance into a different powerpoint to see if the appliance works.
Try plugging a working appliance into the powerpoint to test if the powerpoint works correctly.
If you can confirm the powerpoint is working correctly, and the equipment will not torun on, raise a service call with the manufacturer.
-
If the gas supply is not flowing, check the gas supply is turned on, to do this you must:
Locate the ValveThe isolation valve is usually a small, silver or brass ball valve with a metal handle (often red or yellow). It is typically located behind a bottom storage drawer, in a nearby cabinet, or behind the stove itself
Check the PositionCheck the Handle: Gently try to turn the handle. It should move smoothly to the open position and stop there.
Fully Open (On): The lever is parallel to the pipe. This allows gas to flow freely.
Closed (Off): The lever is perpendicular to the pipe
Verify Operation
Test the Burners: If the cooktop burners work, but the oven does not, the oven-specific isolation valve might be closed.
Inspect for Leaks: If you have just manipulated the valve, it is good practice to ensure no gas is escaping. Use a soapy water solution around the joints—bubbles indicate a leak.
If you smell gas, turn off the main supply, do not use electrical appliances, and call a licensed gas-fitter.
If the gas supply appears to be turned on check it is servicing other equipment correctly.
If you have tried these tests, and the problem is isolated to this piece of equipment, raise a service call with the manufacturer.
-
If the gas is flowing but not igniting, check the appliance is plugged in and powerpoint switched on..
Check if the igniter or burner is not blocked by food debris, flooding or oil build up. Clean burner caps/ports (when cold) and dry thoroughly.
Test to see if the other ignitors are working
You can try the following:
Turn the appliance off, wait 30–60 seconds, then retry.
Reset the thermostat
If you have tried these tests, and the problem is isolated to the one piece of equipment, raise a service call with the manufacturer.

1. Power
☐ Is the appliance still on at the wall or switch?
☐ Has a power switch or breaker been turned off?
☐ Turn the oven off, wait 30 seconds, then turn it back on2. Door
☐ Is the door fully closed?
☐ Is anything blocking the door from closing properly?3. Display / Lights
☐ Is the screen on?
☐ Are there any flashing lights or error messages?
→ If yes, write down what you see4. Heat / Cooling
☐ Was the appliance being used heavily before it stopped?
☐ Turn it off and let it cool for 15–20 minutes, then try again5. Gas ovens only
☐ Is the gas turned on?
☐ Are other gas appliances working?6. Timers
☐ Has a timer finished or auto-stop turned the oven off?
☐ Reset the program and try again5. Water Appliances only
☐ Has the water turned on?
☐ Are other water use appliances working?Still not working?

1. Check power & machine status
☐ Is the dishwasher powered on and not in standby mode?
☐ Has the machine been reset? (Turn off for 30 seconds, then restart.)
☐ Is the door fully closed and latched? (Most units will not fill if the door is not secure.)2. Confirm water supply is on
☐ Is the main water tap to the dishwasher fully turned on?
☐ If connected under a bench or behind the unit, check it hasn’t been accidentally closed
☐ If possible, confirm other equipment on the same water line is receiving water3. Check inlet hose and connections
☐ Ensure the water inlet hose is not kinked, twisted, or crushed
☐ Check the hose connection at both ends is secure
☐ Confirm the hose hasn’t been moved or pinched during cleaning or repositioning4. Check for blocked inlet filter
☐ Locate the inlet filter/strainer (usually at the water connection point)
☐ Turn off water supply before checking
☐ Clean any sediment, scale, or debris
☐ Refit securely before turning water back on(This is a very common cause of “not filling” issues.)
5. Check water pressure
☐ Has there been any recent plumbing work or water outages?
☐ Is water pressure lower than normal elsewhere in the premises?
☐ Low pressure can prevent the unit from filling correctly6. Look for error codes or indicators
☐ Are there any error messages, warning lights, or alarms displayed?
☐ Note the exact code or light pattern7. Check detergents and chemicals
☐ Are chemicals and rinse aids correctly connected and not empty?
☐ Some machines will not fill if chemical systems detect a fault8. Has anything recently changed?
☐ New staff operating the dishwasher?
☐ Cleaning or maintenance just completed?
☐ Any changes to water supply, plumbing, or chemicals?If the issue persists
If the dishwasher still does not fill after completing the above checks, please log a service request and include:
Which checks were completed
Any error codes displayed
When the issue started
This helps us diagnose the fault faster and reduce downtime.
-
1. Check the power & cycle status
☐ Has the machine been opened mid-cycle?
☐ Try turning the machine off for 30 seconds, then restarting.If unknown re-start machine and run the shortest cycle to see if it drains once finsihed..
2. Inspect and clean the filters (most common cause)
☐ Remove and clean all internal filters and strainers
☐ Check for food scraps, labels, broken glass, or debris
☐ Refit filters correctly — the machine may not drain if filters aren’t seated properly3. Check the drain area and sump
☐ Look inside the drain/sump for visible obstructions
☐ Remove any debris using gloves (never tools)
☐ Confirm nothing is blocking the drain opening4. Check the drain hose
☐ Ensure the drain hose is not kinked, crushed, or bent
☐ Check that the hose hasn’t been moved or pinched behind the machine
☐ If connected to a sink or floor waste, confirm that point is not blocked5. Verify water levels
☐ Is the dishwasher overfilled with water?
☐ If so, this may indicate a blockage or level sensor issue — note this when reporting6. Check for error codes or warning lights
☐ Are there any error messages, flashing lights, or alarms?
☐ Write down the code or message exactly as shown7. Has anything recently changed?
☐ New staff using the machine?
☐ Different detergents or chemicals introduced?
☐ Heavy soil load or unusual items washed?If the issue persists
If the dishwasher still isn’t draining after completing the above checks, please log a service request and include:
What checks were completed
Any error codes shown
