Troubleshooting your dishwasher

Dishwashing issues

Here are the top five problems people encounter when they empty their dishwasher. We tell you what causes them and how to sort them out.

Cloudy glasses – In hard water areas mineral deposits – mainly calcium and magnesium - can build up over time leaving a film on glassware. Hard water can also damage your dishwasher. So, to protect both your glassware and your appliance from lime scale, use salt to increase the effectiveness of your machine’s built-in water softening system. Frequent dishwashing can also cause corrosion on glassware adding to the cloudiness issue. Putting Finish® Jet-Dry in your cycle will combat the problem and help to leave glasses sparkling.

Salt taste – If you notice cups taste salty you may have overfilled your machine’s detergent dispenser. If you spill any Finish® Dishwasher detergent when you’re refilling make sure you flush it away. Check the lid of the dispenser is on tight and nothing is leaking during the wash. If the problem persists you may need to call an engineer as a valve that allows water into the machine’s softener could be blocked.

Gritty tableware – If your dishes feel gritty and are mottled with specks of food it may be a stacking issue – you may have overloaded the machine, stacked plates too close together or put items on top of one another. Think about how you load your dishwasher to allow maximum water circulation. You may also want to check the spray arms are not blocked – run water through them to see if any of the small holes are compromised by dirt and food debris. You can use a toothpick to clear them. Also give the filter a wash to ensure dirty water can drain away properly. Before you use the machine again use Finish® Dishwasher Cleaner to get rid of any grease and limescale which can build up in your appliance. A clean dishwasher means clean dishes.

Stained cutlery – If acidic and salty food is left on cutlery too long it can cause marks and tarnishing so it’s always a good idea to use a pre-rinse program if you’re not ready to put your dishwasher on a full cycle straight away. Also, you shouldn’t over-fill the cutlery basket. If cutlery touches each other – particularly if it is stainless steel and silver – it can cause tarnishing and pitting (the roughness you feel when you run your finger over it). Finish® Detergent Booster will speed up the drying process. Finally, use Finish® Quantum Max Shine and Protect detergent, which offers in-built silver protection to help overcome these problems.

White spots on your glasses and dishes – Again this is due to hard water so check your appliance’s salt levels, top up the rinse aid and always use Quantum Max detergents which offer built-in protection against spots and marks while delivering a sparkling shine.
