Dishwasher Issues | Best Pick Reports
Dishes are not getting clean. Try
a more powerful cycle. While lower, more gentle cycles are more energy
efficient, they may not be strong enough to remove the food residue and
grease from all dishes.
Incorrect loading may be a factor. Do
not place dishes in a manner that blocks the rotation of the spray
arm(s). Allow for separation between loaded dishes, as water cannot
clean areas that it cannot reach.
Low water temperature is another possible cause of poorly cleaned
dishes. Check to see if your hot water temperature is set too low. The
recommended temperature setting is 140°F for cutting grease and
dissolving soap. To measure the temperature of your hot water, insert a
meat thermometer into the hot water stream flowing from the kitchen
Another reason why dishes may not be getting clean is that the water
in the dishwasher is not as hot as the water you measure in the sink.
As water sits in the pipe, it loses its heat. When the dishwasher is
turned on, it fills partially with hot water and partially with the
water that has been cooling in the pipe. To limit this problem, try
running hot water at the kitchen sink before starting the dishwasher.
Alternatively, a closed-loop circulation pump could also fix this
issue. These systems slowly bleed hot water from the hot water line
just below the kitchen sink and return it to the hot water heater for
reheating through a second, smaller waterline. A small pump drives the
circulation. Because closed-loop circulation systems do not waste
water, they are also more eco-friendly than running the sink water.
Clogged drain screen or filter. Sometimes
the drain screen or filter in the base of the unit becomes clogged with
food particles. An indicator is standing water in the dishwasher after
the cycle is complete. Depending on your unit, you may be able to clean
the screen or filter yourself. However, never reach into the area below
the lower rack before the heating element has cooled.
Clogged or jammed spray arm. During
the cycle, the spray arm spins and sprays water onto the dishes at
different angles. Clean any plugged spray arm holes and make sure the
arm spins freely. Again, make sure to wait until the device has cooled.
