Dishwasher will not drain I think it:s the pump

I think that light combination means "Drain error". Most comonnly caused by something hard getting down into the drain pump, blocking or partially blocking the drain pump impeller or the check valve inside the drain hose right next to the drain pump.

HI,

If the water doesn't drain from your dishwasher, check these:


Drain line/air gap A clog in the drain line or air gap (if there is one) is the usual reason that a dishwasher won't drain. Often the problem is at the point where the drain line attaches to the garbage disposer or household drain line. If you remove this line, you can clear any debris from the hose or hose connection. Be sure to reattach the hose before starting the dishwasher again.

Pump Your dishwasher pump ejects the water. The pump is usually mounted directly to the motor, then attached to the bottom of the dishwasher. You can reach the pump from inside the dishwasher, but first you need to remove the lower rack, the spray arm, and the spray arm support.

Look for an impeller--a round plastic fan blade-type of device that spins around. This is the wash impeller, which forces the water through the spray arm. Beneath the wash impeller is the drain impeller, which is similar in size and shape to the wash impeller. The drain impeller pushes the water toward the drain port. These components make up the pump. If any of the pump components are defective, you need to replace them.

Drain valve and/or solenoid Many dishwashers use a drain valve with an electric solenoid. When electricity flows to the solenoid, the valve opens and diverts the water to the drain. Sometimes the solenoid, or the diverting lever, sticks and prevents the dishwasher from draining or filling properly. Try to free up the solenoid to lubricate the lever. Otherwise, you may have to replace the solenoid or pump assembly. With these systems, the motor always rotates in one direction. When it's energized, the drain valve diverts the water.

Other dishwashers simply reverse the direction of the motor to drain the dishwasher. These units don't have a drain valve. Instead, there's a drain hose connected directly to the pump housing.

Belt One brand of dishwasher uses a belt to drive the pump. If this belt is broken or has fallen off, replace it.

Motor If the motor isn't turning or working, the unit won't drain. First check to be sure you have power to the dishwasher. If not, see the section "It doesn't work at all." If the motor hums but doesn't turn, it may need to be replaced.

Some dishwashers are susceptible to getting stuck if you don't run them regularly. If you haven't run the dishwasher for more than a week, you may need to manually spin the motor to free it up. If the motor is defective, you need to replace it. Dishwasher motors can't be serviced.

Timer Part of what the timer does is control the motor and drain valve. If the timer doesn't work properly, the water may not drain and you need to replace the timer. This problem is uncommon.

Hi
Dishwasher not draining issue usually occurs due to kinked drain pipe, clogged drain filter or drain pump. First make sure that the drain is not clogged and remove clogs if present. If no visible lint is present then remove the lower front access panel to check the drain filter and drain pump for any clogs, you'll need to clean the drain filter and drain pump completely. Also, check for any food pieces stuck near the pump impeller & clean the chopper assembly. Please note that dishwashers don't drain out the complete water such that heating element doesn't overheat. Hope this helps... Please post back for any further assistance.

You could just need to clean out the sump if the drain pump impeller is jammed. Below is a link to a video you can download that will show you how to repair a Bosch Dishwasher that isn't draining.

Good luck

Hi

If no visible lint is present then remove then turn off the dishwasher and remove the drain hose and check for any visible clogging. If still not visible then the drain filter or drain pump is clogged and you'll need to clean the drain filter and drain pump. Also, check for any food pieces stuck near the pump impeller.

problem may be
1)drain block(inside the trp).
2)if drain pump is auto (or)manual.if drain pump is present check the pump is working.

on all dishwasher think of them as a simple gutter system. the water only has one drain. At the bottom, if the pump can't pump out the water, its simply a bad pump or a clogged drain hose. Food particle can clog the "drain screen", use a good quality shop vac, clean 'drain screen', remove drain hose and clean thoroughly. If the hose goes into your drain pipe, remove that and clean that really good with snake it its metal or a strong 1/2 zip tie if its plastic.

hi Dishwashers usually run on 115-volt or 120-volt power. The water they use comes directly from the water heater, and wastewater is drained into the sink's drainpipe. The dishwasher is not connected to the cold-water supply. For best dishwashing results, set the temperature control of the water heater to no less than 140 degrees Farenheit. Water cooler than this usually doesn't get the dishes clean, unless your dishwasher is a newer model that preheats incoming water. The water shutoff for the dishwasher is typically located below the adjoining sink.

this can happen after inactivity. the circulation pump seal sticks and wont turn . when the dishwasher starts to fill the circulation pump is pulsed on to see if the preasure switch switches over (to see if water is getting into the dishwasher) if the pump does not turn there is no preasure and the machine stops thinking no water has entered. turn pump by hand to cure.

It's not easy. I just look at my sister-in-laws and I think the tub needs to come off. I plan on working on it this week.
