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 start up, raise a service call with the manufacturer.

VERIFY OPERATION
Test the Burners
☐ Is the issue isolated to one or all one or all of the appliance burners? Is the oven burner working?
☐ Turn off the gas and check if there is a specific isolation valve that may be blocked or closed.
CHECK MAIN GAS SUPPLY IS ON
Locate the Valve
The isolation valve is usually a small, silver or brass ball valve with a metal handle (often yellow). It is typically located behind a bottom storage drawer, in a nearby cabinet, or behind the oven itself.
Check the Position☐ Check 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
☐ If the gas supply is correctly turned on, check it is servicing other equipment correctly.
☐ If the problem is isolated to this piece of equipment only, raise a service call with the manufacturer.
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 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.
System Reset:
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.
-
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 onDOOR
☐ Is the door fully closed?
☐ Is anything blocking the door from closing properly?DISPLAY/LIGHTS
☐ Is the screen on?
☐ Are there any flashing lights or error messages?
→ If yes, write down what you seeHEAT/COOLING
☐ Was the appliance being used heavily before it stopped?
☐ Turn it off and let it cool for 15–20 minutes, then try againTIMERS
☐ Has a timer finished or auto-stop turned the oven off?
☐ Reset the program and try againWATER APPLIANCES ONLY

CHECK POWER AND 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.)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 waterCHECK INLET HOSE & 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 repositioningCHECK 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.)
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 correctlyERROR CODES & INDICATORS
☐ Are there any error messages, warning lights, or alarms displayed?
☐ Note the exact code or light pattern☐ Refer to manufacturers guide error codes
CHECK CHEMICAL AND DETERGENTS
☐ 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 the manufacturer diagnose the fault faster and reduce downtime.
-
POWER AND 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..
FILTERS
☐ 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 proper☐ Has the filter been changed in accordance with maintenance guide
3. DRAINAGE AND SUMP
☐ Look inside the drain/sump for visible obstructions
☐ Remove any debris using gloves (never tools)
☐ Confirm nothing is blocking the drain openingDRAIN HOSE CHECK
☐ 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. WATER LEVELS
☐ Is the dishwasher overfilled with water?
☐ If so, this may indicate a blockage or level sensor issue — note this when reportingERROR CODES & WARNING LIGHTS
☐ Are there any error messages, flashing lights, or alarms?
☐ Write down the code or message exactly as shownHAS ANYTHING RECENTLY CHANGED?
☐ New staff using the machine?
☐ Different detergents or chemicals introduced?
☐ Heavy soil load or unusual items washed?STILL NOT WORKING?
