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

Not sure what the actual model number is but usually the F1 error with Fisher and Paykel dishwasher means water has entered the flood switch located at the base. This could be due to leaky hoses or water leaking through the door or lid seal. Wait for a day or two until the water evaporates and try again. Otherwise you will have to dry out the flood switch and then try again. Location of flood switch will depend on your model. For double drawer dishwasher you will have to take the bottom drawer out from the housing and the switch is on the floor of housing. But make sure you take the mains power chord out before touching the insides of dishwasher. Will also need to find the cause of the leak. Other reason for F1 could be loss of power to top dishdrawer if you have double drawer. But in that case the top drawer will have no lights on. The power board is located on the base of housing under bottom drawer. Once again do not touch inside of dishwasher without shutting off mains power.

Sorry did not see your problem report earlier. If you have checked the sensor under the bottom drawer and it is dry, then F1 is caused by top drawer power filter fault. This means the bottom drawer controller is giving the F1 error but the top drawer controller has no power. Can you confirm this.

The F1 error coming on top drawer when operating bottom drawer is due to the thermal fuse blowing up on the bottom drawer and shutting controller power.

The thermal fuse could have blown either as a normal component failure or heater over heated due to thermostat failure. In any case this can be repaired by replacing the whole heater assembly as all the parts are integrated.

This is at the underside of the drawer and will need a technician to replace unless you are very familiar with repairing electronic dishwashers. The part look like this.

The way you have described the onset of the F1 error is not due to flood switch. You can confirm that the lights on the bottom drawer are out even though the top drawer is showing F1 and beeping.

If problem was flood switch then both drawers would show F1.

Hi

Thanks for using FixYa. F1 error means that the flood switch has been activated. You’ll need to reset it by powering off the breaker or by unplugging the unit from the power socket and mains for more than five minutes. Please check that there is no blockage in the drain hose and it is not raised higher otherwise the water will run back to the dishwasher. Also perform the following procedure---

• Unplug power and remove bottom dish drawer
• Use a Sponge and dry all the excess water underneath
• Remove circuit board cover
• Dry all around and underneath as much as possible
• Apply hairdryer for 10-15min

Please do rate the solution if the issue is resolved or else revert for further assistance.

the f1 is the flood sensor....a leak has accured....either a dish to larger or lid motor has failed. will need to remove bottom drawer and soak up water and then let air dry for a day or two....turn off the breaker this will keep it from beeping and running the pumps....after drying unit will run, but need to watch the dishes you put in drawers.

leave it unpluged to stop for now, the machine has detected a leak and is constantly running hte pumps within the drawers to try to remove any water.. problrm is the water detector is in bottom under the lower drawer and htere is no pump to remove that water ..canbge a fickle machine as far as leaks are concerned, but the easy reason is usually misloading of the drawer itself, was an item put in that was too tall , preventing the lid from coming down and sealing off drawer causing water to overflow down the side??? there should be(so logn as no previous repairmen have taken it) a tech/trubleshooing guide taped to teh back wall behind the lower drawer, which is easily removed by unlocking hte hinges on either side of the front of drawer, explained in your manual

Hi,

It would seem to be in an endless loop (firmware glitch). Initially, pls try:

• unplug from the mains or switch off the breakers for a couple of minutes;
• plug back in/switch on the breakers say after 20 minutes;
• press POWER to turn drawer on;
• Press and hold (at the same time) both the POWER and ECO buttons for a few seconds;
• a five minute demonstration wash cycle will come on;
• press POWER again to put unit on standby, all the LCD segments will start flashing (and light up);
• press and hold START/PAUSE for a few seconds to hear confirmation beep/tune.

Alternately, should you have the two-drawer, open any drawer and look at the wash intensity/economy buttons. Now press them, one at a time, alternating between the two, at even timing.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards. Thank you for using FixYa.

Hi there, If you have had an F1 you need to dry out the product in order to reset the flood switch. This is a simple process as follows: 1. Ensure product is disconnect from wall so that it has no power. 2. Open the bottom drawer and put your hand in through the gap where the bottom of the bottom drawer comes out and feel the base of the cabinet that houses the drawers for water. 3. If there is water present dry it out as much as you can with paper towels or old rags. This machine is designed to drain all water to the front of the base of the cabinet away from the flood switch that sits at the back left corner of the cabinet base that the drawers are fitted into. 4. When you have base of the cabinet dry you need to ensure that the switch has not moisture on it in order for it to reset and allow you to start using the product. This can be done 2 ways: 1. leave bottom drawer open for 24-48 hours to allow natural air circulation to dry out the connection. or 2. position a hair dryer to blow air into the back left corner of the base of the cabinet and dry it out quicker. This still make take up to 6 hours as the flood switch had a protective cover over it to try to prevent F1's for small spills. 5. When the product had been dried out, important that you make sure it has, when you switch on the machine the F1 should be gone and ready to use. Please run each drawer seperately on a rinse cycle to confirm to yourself that it flooding was possibly caused by something blocking the sprayarm, or something stacked too high or something got stuck in the pump temporarily stopping it from draining effectively or the product suddsing too much from spilt rinse aide in one of the drawers. If each drawer runs successfully you should be in the all clear to start using it again. Please note though: if something blocks the spray arm that is directly linked to the pump your drawer will flood as a result. If you have something stuck in the pump peventing it from draining effectively ie a toothpick or piece of broken crockery this will cause your product to flood, but you will hear an louder than normal sound when the pump is running. And finally if you spill rinse aide in your drawer when filling it clean all spilt rinse aide to prevent unit from over sudsing when running. Regards KAR-Ltd
