According to an engineer, there could be a simple explanation for the issue, and what can be done about it.‌Posting on Facebook, British Gas revealed blockages around the spray arms could cause the issue. The post explained: "Tired of your dishwasher leaving bits of food behind? Before you run another cycle, check your spray arms for blockages!"‌In the video, a British Gas engineer demonstrated how to complete the check. He told customers: "If your dishwasher is leaving food on the plates, check this before you run it again. Don't waste electricity running a second cycle.‌"The problem is usually your spray arms. Hard water scale and tiny bits of food block the water jets, meaning your dishes don't get a proper wash. You can actually just pop these arms right off."Take a pin or a toothpick and poke it through the blocked holes to clean them out. Give the arm a flush under the tap and clip it back in. You get a perfect clean first time, saving energy and water."‌Homeowners can find more cleaning tips on the British Gas website. Sharing a list of spring-cleaning jobs, the experts highlighted several kitchen appliances that can benefit from regular care. British Gas explained: "Fridge and freezer – remove old food, clean shelves and defrost your freezer."Oven and microwave – clean out food debris and wipe down the surfaces. Dishwasher – clean the filter and wipe down the seals on the door. Washing machine – run an empty cycle with white vinegar to remove any mould."Additionally, most supermarkets sell dishwasher cleaner designed for regular use. For instance, Tesco sells Tesco Dishwasher Cleaner for £2.70. The description claims: "Eliminates grease and limescale. Helps prevent drain blockages. Tesco dishwasher cleaner. Use once a month for a healthier machine."‌One reviewer praised: "This product left my dishwasher sparkling clean and a lovely fresh smell." Someone else replied: "Keeps your dishes sparking clean! Great quality; use it monthly to keep the machine fresh."Would highly recommend." Another fan wrote: "Cleaned dishwasher perfectly, smelled clean afterwards. Good price compared to market leader.
