Help - Beko dishwasher tablet not dissolving
My Beko dishwasher (DVN05C20W), about 18 months old — the detergent tablet is left sitting in the dispenser undissolved at the end. Is this a common fault on these?
1 Answer
Yes, that can happen on Beko dishwashers, but it is not usually a “common model fault” as such. More often it is caused by poor water circulation, the dispenser flap not opening properly, or the wash not getting hot enough.
Before checking anything internal, isolate the dishwasher from the mains.
1. Check the obvious first Make sure nothing tall in the lower basket is stopping the detergent flap from opening fully. It is very common for a tray, pan handle or plate to block the dispenser door.
2. Try a hot programme If the machine is washing in cold or only lukewarm water, tablets often do not dissolve properly. Run a hotter programme and open the door carefully partway through the wash to see if there is proper heat and steam.
3. Check the spray arms Remove and clean both spray arms. If the holes are blocked, water may not be reaching the dispenser area strongly enough to wash the tablet out.
4. Clean the filters A blocked filter system can reduce wash performance. Remove and wash the filters thoroughly under the tap.
5. Look at the dispenser itself Check for detergent residue, a weak spring, or a sticky flap. If the dispenser door is not popping open smartly, the dispenser assembly may be faulty.
6. Consider the wash motor/circulation issue If the tablet is still sitting there and the wash action seems weak, the circulation pump may not be moving enough water.
If it is heating poorly, not spraying properly, or the dispenser mechanism is faulty, it will need further diagnosis. For any internal electrical checks, use a qualified appliance engineer.
