Dishdrawer The top drawer of our dishwasher has stopped working. It has been working fine for about 18 months but now it seems to have no power coming through to it. The bottom drawer is still working fine. There have been no electrical surges that we are aware of.

The most logical explanation is the controller in top drawer has packed up or the power board located at the base of dishwasher housing (under bottom drawer) has partially packed up and stopped supplying power to the top drawer controller. But another explanation is that the thermal relay in the top drawer (located inside the heater element assembly has cut off. This stops power to the controller. This is the most expensive to fix as the entire heater element assembly has to be replaced as the thermal relay is not separately accessible. How you want to isolate the problem and fix it depends on how comfortable you are with fixing electrical and electronic systems. This is a very sofisticated dishwasher and a small mistake is irreversible. By the way you can open the drawer by forcing it open but keep in mind not to try to shut it firmly again until you restore the controller power. Otherwise the lid seal or actuator motors will be damaged. Whatever you do, make sure the mains power is turned off if you work on the dishwasher circuits.

Some sensors on the unit are telling the controller there is a fault.
Most likely the sensor checking the drawer is open or close is giving a fault. It is likely the drawer has come off the rail.

the power board at the base of the dishwasher under bottom drawer appears to have blown up. Take the bottom drawer out carefully to access the power board. Make sure the mains power is turned off.

The reason the bottom drawer is not getting back in is that lid seal actuators are stuck as the motors are in close position. Will reset to normal position once the power is restored. So don't try to push the drawer in as the lid seal will be damaged.

Unfortunately the power is distributed from the inside to the two drawers.
You will have to address the cause of the problem in the top drawer.
If you are good at electric repairs you could disconnect the power from the dishwasher power board itself, but this is not for the faint hearted (no offence). Might be helpful if you can provide a little details about the problem with top drawer. Generally if you are getting F1 message on the panel on bottom drawer and top drawer display is blank (ie no power), then the power board at the base of dishwasher is blown and needs to be replaced. Please clarify model number as the one you provided is for single drawer unit. Make sure the mains power is turned off when you work inside the diswasher.

The dishdrawer is a very sophisticated dishwasher and is very sensitive to dirt collecting inside and in the drain hoses. My suggestion would be to first clean the drawers from inside with damp cloth, especially around the top panel. Buy Finish dishwasher cleaning kit (one for each drawer) from the supermarket. Select longest cycel on dishwasher and run each drawer with the cleaning kit inside as per instructions on the kit.
See if this makes any difference.

Describethe inside of unit,any wear on it anywhere, the rack the dishes go on is it plastic coated? is it wore with rust comeing though on tips here and there?

Water has collected at the base of the dishwasher under the drawer.
This triggers a flood switch and causes the F1 error.

Turn the mains power off and extend the drawer out as much as possible. Take towels to dry the base from inside. Also use hair dryer ot dry out the flood switch mounted at the base.

Turn the power on and see if there is any difference. The cause of water collection could be many. Foam in detergent or kink in drain hose or drawer door gasket leaking etc.

By no power you may be implying there is no display etc and the swithces are not working. Most likely the controller of the top drawer has had it. The controller is mounted on the front of the drawer behind the door panel. Hope things are better than that.

Please rate me

there is only one power supply or input so you need to find out where the power stops from the bottom to the top drawer
