Dishwasher Problems

A dishwasher is a device used to clean dishes, plates, spoons, glasses and other eating utensils. The mechanics used to clean utensils is a spray of hot water and detergent on to the dishes followed by a spray of clean water to remove any soap residue. This is followed by a drying period with circulated hot air. Some dishwashers have multiple washing, rinsing and drying cycles. While dishwashers are usually installed in restaurants, they are now more commonly used, in a smaller capacity, in households as well. These machines are very useful and may be used daily. Common dishwasher problems could include leakage, noise or residue.

Listed below are a few questions answered by the Experts on issues related to dishwasher problems and troubleshooting.

Is a three hour cycle on a Bosch dishwasher considered a normal cycle?

A normal cycle would be approximately between two to two and a half hours including the drying cycle. When the cycle crosses three hours it could indicate a problem. The main reason for the cycle to get extended would be if the dishwasher is not heating the water. To rule out this issue, check if steam escapes when you open the door of the dishwasher. This is a common problem with dishwashers and is caused by a short circuit in the relay to the control board on the inner side of the door. The relay is responsible for transmitting power to the heater. When it fails, the dishwasher does not function efficiently. Hence it extends the cycle in an attempt to heat the water. The cost of this unit is $150 with shipping charges being additional.

How do I access the control board of my Bosch dishwasher?

To gain access to the dishwasher’s control board, you need to locate the screws along the border of the door after opening it and unscrew them. Remove all of them except the two located near the bottom hinge. These screws only need to be loosened. Thereafter, remove the two screws on either side of the control panel. Once this is done, the panel will come out easily allowing you access to the control board. Press the three tabs on the bottom of the control board thereafter to remove it.

My Asko dishwasher usually retains a small amount of water in the cylinder after it finishes washing and starts to emit a bad odor. Why does this happen?

Dishwasher models from Bosch, Miele and Asko are designed to retain a small amount of water inside the dishwasher to prevent seals and pumps from rotting or cracking. Using a dishwasher cleaner such as “Dishwasher Magic” on an empty cycle can help clean the inside of your dishwasher and get rid of the odor. To prevent it from recurring, leave the door of your dishwasher slightly open and not clicked shut so that fresh air can circulate through, thereby reducing the chances of odor.

Recently the water softener in our house broke down causing the toilet pumps to malfunction due to salt buildup. Now water is not entering my dishwasher. Probably the water line is clogged. Can I flush it out?

First remove the screw kick panel and unplug the dishwasher or turn off the circuit breaker. Then disconnect the water supply to the dishwasher and get the electronic water valve removed. After you do this, attempt to flush the screen under the faucet. If this doesn’t sort the problem out, it is possible that you may need to replace the valve. On the other hand, if the dishwasher is definitely receiving water from your water supply pipe, the problem could either be with the electronic valve beneath the washer or with the float switch which could be jammed in the “up” position. Open the dishwasher door and look for a plastic circular float device at the front corner of your dishwasher. Move this up and down and ensure it remains down. If there is no change and there are no wires that have suddenly become unplugged, the problem probably lies with the electronic water valve that needs to be replaced.

My Bosch dishwasher is not washing and seems to be stuck. When I add water manually into it, it is immediately draining the water. What is the reason?

This kind of issue is referred to as “flood mode” where the water has entered the base pan below the dishwasher tub making the unit drain continuously. The reason this happens is usually due to excessive detergent usage leading to an overfilling of the tub or a clogged drain. To address this problem, deactivate the dishwasher and tip it at an angle of 45 degrees, allowing the water to drain out of the base pan. You can place a towel under the dishwasher to absorb the excess water and prevent spillage. After removing the water, plug the dishwasher on and pour a gallon of water into it. If it continues to drain, there is still water remaining in the base pan to be removed. Another option would be to not use the dishwasher for a week. During this time the water collected in the base pan should evaporate allowing the dishwasher to work again.

Apart from the various scenarios detailed above, you may have come across many other dishwasher problems. These could be issues such as the dishwasher making a lot of noise, leaking water or not cleaning efficiently. Sometimes you can manage without a dishwasher by washing manually but at other times it can be very inconvenient. To understand what you can do to resolve your issue with minimum time, effort and resources, consult with an Expert to get the help and guidance you need.
