the dishwasher (a GE model with hard food disposer and god knows how many
filters) sometimes gets really clogged and we have to pour vinegar in it and
drain it many times and so on.
other times, however, I open it and there's water on the bottom. I start a
cycle and cancel it, forcing the water to drain. the water drains
why would the water drain now but not 5 minutes earlier?
other times it won't drain when I cancel the program, but if I leave the
program go for a while (basically washing nothing) then it drains. what does
this do? are the filters cleaning themselves during a wash? should I
therefore regularly run the dishwasher empty to keep the filters clean?
Probably a bad timer. Dishwashers generally run mainly on time. The
duration of each fill or wash or drain cycle is controlled by the timer. So,
the drain cycle at the beginning of the wash is working OK, hence the
complete drain, but a bad contact within the timer at the final drain cycle
is causing it stop prior to completely draining.
The timer can be replaced, if the dishwasher is worth it otherwise.
As for the filters, they are generally self-cleaning. They filter the food
particals from the water as it is pumped out the jets during the wash and
rinse periods, but the water is pumped back the otherway thru them on drain
cycles, washing the particals down the drain.
A few other items to check:
You run the sink disposal prior to each wash. Since the DW probably drains
into the sink disposal, if there is food in there it could prevent the DW
from draining properly.
Check the drain hose under the sink. It should be pulled up higher than the
highest water level possible in the sink. This will keep water that drains
from the sink from flowing into the DW.
Try not putting dishes with too much food left on them in the DW. I know
Maytag says they'll handle anything, but my thought is, that's why I put the
disposal in the sink - to dispose all. I put the Dishwasher in to do that -
Intermittant problems are the worst!! :(
Some draining info and issues that may help....
Scrape away large pieces of food, bones, pits, toothpicks, etc. Burned
on food should be loosened before loading. Empty liquids from glasses
and cups. Foods such as mustard, mayonnaise, vinegar, lemon juice and
tomato products may cause discoloration of stainless steel and
plastics if allowed to sit for a long period of time. Unless the
dishwasher is to be operated at once, it is best to rinse off these
food soils. Load racks so that large items do not prevent the
detergent dispenser from opening. If the dishwasher drains into a food
disposer, be sure disposer is completely empty before starting the
