How do you fix dishwasher stopping and beeping.

The Fisher and Paykel DishDrawer Dishwasher (2008, I think) stops and beeps on startup and flashes red. When the drawer is open you can shine a light in and see caustic water on the try below the drawer.

How do you make the dishwasher work again.

Thanks

Are you sure it's the hose Vs a worn seal (your water flow valve could also be leaking). In any case you'll need to locate the problem. Can you unscrew the unit from the counter so you can slide the whole unit out. If you have a drawer unit type that requires a cabinet you could create a frame with some scrap wood to hold it off of the floor. With the unit running see if you can see the source of the drip?

What model is it? Any chance you can post a couple of images of the leaky hose and its location?

It turns out the beep is caused by a corroded sensor. The sensor is a small circuit board on the lower tray, I think it senses when there is a leak. In actual fact, the dishwasher was not leaking at all, but water was dripping onto the lower tray, however. Dripping occurs when you stop the dishwasher mid-cycle to put in that coffee cup you forgot in your bedroom. When you stop the dishwasher, it holds the door locked for two seconds so that most of the water on the internal lid drips off, but it is impossible for it all to drip off so, when you pull out the drawer, you get drips on the tray underneath (and the sensor). The water, mixed with dishwasher detergent, is very caustic and after a while the caustic chemicals corrode the sensor and cause it to malfunction. The dishwasher may stop (it shuts down if it detects a leak) or, if the sensor is stuffed, it will beep and the blue LED will turn red and flash and beep.

Prevention:

Do not open drawer-style dishwashers mid-cycle, under any circumstances. Also do not put tall objects in that would prevent the lid from descending all the way when the draw is closed - the lack of seal will allow caustic water to leak out as it is being sprayed around.

Solution:

You may be able to repair this problem by cleaning up the mess, inspecting the sensor for corrosion or deposits of detergent, etc and getting rid of it. Repair any broken or corroded contacts.

If the damage is bad, you will probably need a new sensor board from Fisher and Paykel.
