Question about Bosch SHV4803 Dishwasher

1 Answer

Dishwash cycle takes too long.

The dishwash regular cycle is 280 minutes. It used to only take 86 minutes. I tried running the hot water before turning on the dishwasher, but it did not reduce the time.

My dishwasher suddenly won't wash hot on either the normal auto setting nor the eco one.

Do you find water left in the dishwasher bottom at cycle end???? It sound like your drain line is partially or completely blocked or possibly a bad drain pump depending on model. If it can't drain completely it can't refill with hot water. That will also explain an increase in the cycle time. Some dishwasher add time because it is trying to heat the water up. Its a loosing battle if the water isn't partially hot to begin with.

Cycle starts, but does not fill with water

When I start a new cycle, I first hear the pump run to empty out all remaining water, and after that I hear the motor run for the regular washing cycle, but there is no water in the dishwasher. After a few minutes, the cycle stops, and the washer claims the dishes are 'clean'. When I try starting a new cycle over and over again, about one in 20 times, the cycle will run normally with water. But then the next time, the problem starts all over again. Once a cycle starts correctly, everything works fine, including the rinsing.

TAKES A LONG TIME,

Takes a long time to what? If the entire cycle seems to take forever, one suggestion is to make sure your hot water heater is turned up. Most dishwashers requires the water to be a minimum of 120 degrees before the timer will begin. If you are using a Sani-Wash cycle, then the water need to heat up to 165 degrees. The heater can only heat the water 1 degree per minute, so if the water coming in to the dishwasher is only 100 degrees, it will take an additional 65 minutes before it will even start the cycle. You can also make sure you get the water at the sink hot before you start the dishwasher, this will ensure the hottest water is going in (only fills for 90 seconds).

The dishwash is not washing, it's running but there is no water. The washing cycle is completed but nothing has happen, this recently started.

Sounds like a bad water valve or the water supply is cut off. If the water supply is not cut off then try hooking up 120 volts to the water valve. It should buzz or hum and let water in. If no water goes in then change the valve.

Asko dishwasher d3530. The water in the dishwasher is not hot.

Generally speaking, dishwashers don't heat cold water on their own. Be sure the dishwasher is connected to a hot water supply and that hot water is available to the dishwasher at the START of the cycle.

Often it takes hot water several seconds for house plumbing to deliver hot water to an outlet. If the dishwasher is connected to the kitchen hot water supply, run the water in the sink until the water runs hot before you start the dishwasher.

Dishwashers often have heaters to heat the water even hotter than most home water heaters, but they are not intended to heat cool or cold water. You MUST furnish hot water to the dishwasher from the time the cycle is started.

I've seen houses that take so long for hot water to reach a faucet, the dishwasher is already full (of cold water) before the first drop of hot water reaches it.

Good luck. Hope this helps.

What is the amount of time for a regular wash? Time on the plus wash?

a regular wash should take about an hour and a half. plus wash would be longer only because it heats the wash temp hotter.
wash temp is generally around 140 degrees
and your rinse is around 161 degrees.

your flow through heat assembly heats the water at 2 degrees a minute. so it can take anywhere from and hour and a half to two hours for a full cycle.
try turning your sink on hot water until you feel hot water coming out then start the dishwasher so it doesnt have to heat cold water up to those temps. it should run a little shorter.

Dishes crack when washing and also the time does not set less then 1hr19min.

if dishes are dishwash safe then the water heater is on too hot. if that hot water can hard boil an egg then its too hot.for the time try unplugging it for a minute and plug it back in. that should reset wash options.

I have a Bosch SHV55M03GB dishwasher which does not heat the water. The programme cycle also sticks at the last minute. Any ideas, heater element or control panel? Thanks.

If cycle proceed normally after waiting for a while, then the control is probably OK. It stands by a while because it does not read correct temperature before proceeding.

If the appliance is connected to both hot and cold water, open more the hot water faucet.

If the water is not heating at all, check heating element for continuity, using a tester.

If water is heating regularly, but cycle is still slow, check thermic sensor.

Here are more suggestions from Repairclinic:

The cycles times are too long If your dishwasher's cycle times are too long, check these:

Water pre-heating
Cycle not completing
Water pre-heating Your dishwasher may pre-heat the water. If so, and if the water entering the dishwasher is cool, the heater may take up to half an hour to heat the water.

To avoid the wait, increase the incoming water temperature before turning on the dishwasher. Do that by running the kitchen sink faucet until the water runs hot. Or increase the temperature of the hot water to the entire house at the hot water heater.

Warning! To lessen the risk of scalding, don't set the hot water heater temperature higher than 120 degrees Fahrenheit.

Whirlpool Dishwasher Problem

the dishwasher will probably heat the water the rest of the way for you. depending on the specs and features.
hot water is not likely an issue with the dishwasher itself.
you could have cold water plumbed to the unit by mistake.
also, it could be that it is not fully pumping out, and the water going in is mixing with water in the sump.
try running it for few minutes and then pump it out. start a new cycle and see if you are getting hot water. if not, then at try to confirm that the unit is heating the water on its own. run it for about half a cycle and check the water temp again.
you do need hot water to clean in most units.
for certain this is a plumbing problem that is delivering cold water. and if its not heating, make sure that it should be per manufacturers specs, and call for repairs if its not heating the water.
good luck
