FAQ – Dishwashers

Why won’t my appliance drain?

There may be a blockage. Please check the filter for any obstructions. To locate the filter, pull out the bottom rack in the dishwasher and look at the centre of the dishwasher cavity. This is the filter. Clear any blockages or debris.

If this doesn’t work, have you checked the hose? If it is kinked or blocked then the appliance will not drain.

Is the drain hose fitted in the correct position? If it is laying on the floor before rising to the waste outlet it is too low and the pump will not work.

You can also check that the spigot on the sink outlet has been cut off, allowing water to drain from your appliance.

The dishwasher is too small to fit the dinner plates.

You can make more room for large plates by adjusting the top basket. The top rack is height adjustable and by lifting it into the higher set position you will create more room in the lower rack. Please click here to search for your dishwasher model number and refer to the specific instruction manual for a step by step guide on how to adjust the baskets.

My appliance will not fill and the error message says ‘inadequate water supply’.

Firstly, check that the water supply is on. Then check that the inlet hose is not kinked or crushed and is in the correct position to fill the appliance.

How do you level a dishwasher?

The top of your dishwasher should be fitted right up to the underside of the worktop. This is both for aesthetics and to provide stability for the appliance. Each model comes with height adjustable feet. These can simply be twisted to alter the height of the appliance to suit your kitchen.

The back feet are missing.

Click here to search for your appliance model number and refer to the individual instruction manual for this appliance. Some dishwasher models have one foot, located in the middle at the rear of the appliance. This is operated at the front of the dishwasher by inserting a flat screwdriver into the mechanism and turning it until you reach the desired height.

Help! My cutlery is rusting.

Is the cutlery stainless steel? If not you will need to reduce the salt dosage in order to prevent this happening further.

The appliance is tripping the electrics.

Firstly, check the power supply to the appliance is large enough for the dishwasher. The required power supply is listed on the appliance rating plate.

If this is ok, check the socket to the appliance is not faulty. Please note that we always recommend that this is completed by a competent or qualified person only.

If both are OK, please contact our friendly team to investigate further.

The dishwasher will not start a cycle.

Is the décor door fitted correctly? If the door is holding the appliance door slightly ajar, the door may appear shut but the programme will not be able to start.

Did you open the door to empty the dishwasher before the end of the previous drying cycle had finished? If so, the dishwasher will still think that it has a drying cycle to complete and will not start the new programme. You will need to turn it off and on again to start the new cycle.

Poor wash results?

If you are using all-in-one tablets, which contain salt and rinse aid for the average amounts required in the UK, you may need to try using separate powder, salt and rinse aid for better results.

Are you using the correct wash programme for the load? A heavily soiled load will need more than a quick wash to get it sparkling again, try altering the programme selected.

Are the spray arms blocked? If a tray or pan is blocking the rotation of the spray arm, the dishwasher will not be able to clean effectively.

Is the spray arm nozzle clogged? Try removing and cleaning this part to improve the wash results.

Always use a good quality detergent in your dishwasher.

If the water jet is not reaching the crockery, try arranging the load so that items do not touch each other.

Poor drying results?

Is the rinse aid level correct? Try increasing the level and adjust until drying improves.

Try loading the crockery at an angle so that surplus water can drain effectively.

If you are using all-in-one tablets, which contain salt and rinse aid for the average amounts required in the UK, you may need to try using separate powder, salt and rinse aid for better results.

Sandy/grainy residue?

This indicates that the filters are clogged. Remove them, clean thoroughly and replace. This should rectify the problem. It could also mean that the filter is are not in position correctly. Check this before trying again.

Why are there streaks on the crockery?

This indicates that not enough rinse aid is present in the dishwasher. Increase the rinse aid dosage and adjust until desired results are achieved.

Why are there streaks on the glassware?
