We had this problem a few days ago. We called a repairperson, who recommended unplugging the unit, then replugging. It seemed to reboot it — closes as it should and works fine.

The flood switch is accessed by removing the bottom drawer. The flood switch cover is removed by sliding to the right. There is a release clip underneath about mid point of the cover.

Yes it would be in the drying cycle which goes for almost an hour after the final rinse

Manufactured date is on label attached to washer.

F1 error means flood switch at base of dishwasher under bottom drawer has been set off. This is due to water leakage.
Unsure why the vibration is occuring. Can you please confirm by adding some information in the comments field if the F1 is displayed on both drawers or just one and which one.

Fisher and... | Answered on May 25, 2014

ok , F1 means your flood switch has activated, which is underneath the drawer. now they show the F1 fault because of 2 reasons.1st there is still water underneath drawer causing switch to activate. 2nd your activator board which has the flood switch attached is faulty reading your posting it has been about 15 days since the fault happened. the water should have dryed around switch by now. if there is power to the unit and it is still coming up with F1 fault then possibly you have damaged the activator board. please reply and tell me if you have power on or off at the present time. to fix the problem it is alittle bit involved but i can guide you thru it when you reply .good luck

It is very unlikely the inlet water hose is blocked. Most likely it has thinned out and needs replacement. You will have to take the bottom drawer out to get to it. Make sure the diswasher is disconnected from mains power and the water inlet under kitchen sink is shut. The plastic plugs on each side needs to be pulled out to get the front cover out and access the slide rails on which the drawer slides. Make sure the front cover does not fall as the controller and panel are held in it. Take the tub out and leave on floor. The water inlet valve and inlet hose are mouned at the back wall of housing.

This is a controller fault and depending on the conditions of when it occured, may need replacement of controller itself or some sensor which feeds signal to the controller. Usually if fault keeps repeating or is permanently on and turning mains power off and on makes no difference, then you will need a technician to look at it.

This is a serious problem. Most likely the base of drawer is leaking. This contains the motor and heater units. Refer this diagram.
