Fisher & Paykel Dishwasher leaked

I have a Fisher & Paykel dishwasher that leaked underneath. Not sure which drawer the water came from except that I don't really use the bottom too much. The bottom drawer had muddy water in it. I manually took that out.
Presently we are running a rinse cyle in the top and will do the same for the bottom.

Any suggestions on what could have caused this leak?

The serial number is BLM747067

    I have a twin draw Fisher & Paykel dishwasher, the bottom draw was leaking from the left side of it.I turned it off but the same draw started to do the cycle again without being turned on. The only way to stop it was to actually turn it on but then it started up once again. Next thing i knew both top and bottom draws are flashing F1 at me.I take it that means a "flood fault" so i rang Fisher & Paykel, there is no Authorised sevice centre near me so what can i do to get it fixed as it has only run out of warranty 4 months ago?

    My DD 603w Fisher and Paykel ran a cycle and leaked and is now flashing F1. There is a Y in the drain and the drain itself is clear with good outflow. I added water to the machine and it will pump it out from both drawers as fast as I put it in but it won’t do anything else.

When the F1 error flashing on both dishwasher drawers. Unplug the dishwasher power (it looks like a white cable with three prong situated underneath the sink), that action will stop the beeping. Then look for a pan on the left hand side underneath the two Fisher Paykel DD603 dishwashers this may most likely have water in it and maybe also leaking. Drain it with paper towel. Then, after the pan is dry, plug the dishwasher power back to the wall socket (it looks like a white cable with three prong situated underneath the sink), then the dishwashers is back to its good condition.

From what you describe, drain water from the top drawer is getting into the bottom drawer or waste water from the disposer is backing up into the bottom drawer.

1. Each drawer has its own drain hose. Each hose should terminate at the drain point with a 'Y' adapter.
2. Inspect the drain point (under the sink where the drain pipes are) to make sure this 'Y' adapter is present. (you should see two drain hoses from the DW). If not present, then the DW drain lines are not installed properly. (Someone took a shortcut and installed the 'Y' adapter behind the DW)
3. If terminated properly, make sure the drain hoses extend upward as they leave the drain point.

It is important the drain lines are connected properly to ensure proper drainage from the DW. Consult the installation manual for complete details.

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

I have a Fisher Paykel dishwasher with water in top drawer

You need a Air gap kit designed by Fisher and Paykel to address this problem. It is pricey but it is worthy. I used this and very happy with it since no back flow problem from one while other running. Here is a link to order it.

Fisher paykel dishwasher is starting on its own. Will not stop Both drawers . Need help and approximate cost to fix.

Not sure if you are getting any fault codes on the display.

The most common problem is water getting on the base of the dishwasher.

Turn the mains power off. Extend the bottom drawer out as much as possible and dry the base with towels and hair dryer.

Water can leak if the drain hose is cracked or is kinked. Have it checked.

My fisher paykel DD S03SS dishwasher leaks from the top, & drain

The drawers should not leak unless there is a problem with the vacuum seal. Try cleaning the edges of the doors and operate. You should feel the vacuum is holding the doors. The seals could be faulty or vacuum system may be faulty.

About not draining completely - a possibility is the common drain hose after the U adapter being clogged. Remove the clamp and pass a flexible wire coat hanger towards the main drain pipe. If both drawers are not draining then it is unlikely the drain hose between the U clamp and the dishwasher is clogged. Also make sure the height of inlet water pipe and drain outlet is as specified in the installation manual

Hi Both drawers show error F1 flashing beeping with rinse light on and both pumps run after power is applied to machine

F1 error indicates flood switch in base has activated, meaning machine has leaked. This causes machine to drain continously, and can only be stopped by switching off power. Not easy to fix if you don't have experience- bottom drawer has to be removed to access flood switch, then machine needs to be test run and checked for leaks. Best to call the professionals!!

F 1 Error, blinking, beeping and will not stop even when turned off, so we had to turn the circuit breaker off to stop the noise.

You have a leak.
Either from the top lid seal or bottom lid seal. A s time goes by the water level activates the sensor causing the beep. It won't do anything until you fix the leak.
