F8 means you have a blockage in your drainage pipe

Hello

your Whirlpool dishwasher stopped draining mid-cycle, check your circuit breaker or fuses. The cycle won't complete if the power is interrupted. Reset the circuit breaker if tripped, or change out any blown fuses. Fully close the dishwasher door, and restart the cycle if you opened up the door. If you have not used the dishwasher in a while, the motor may be stuck. Open up the main housing, and rotate the motor until it turns freely. You must replace the motor if it's corroded or won't move since it's unlikely that you can fix it.

Pump

The pump is located underneath the lower rack and spray arm. This component is responsible for pumping water out of the dishwasher once the cycle is complete. If the pump isn't working, verify that it is not clogged with debris. Use a toothpick or plastic utensil to remove food particles from it. Check the pump impeller. If a section of it is broken, get a new pump since the impeller is difficult to fix.

Clogs

Clogs in the air gap or drainage hose prevent water from leaving the tub. Clean these components and the water inlet filters, if dirty. Examine the drainage hose, and straighten it if it's kinked. If the hose is badly crushed, you must replace it. Unscrew the drainage hose from the dishwasher to clean it, but reattach it before you restart the cycle. Run the food waste disposer if it's connected to your Whirlpool dishwasher. Remove the knockout plug from the disposer if you have just installed the disposer or dishwasher.

Drain Valve/High Drain Loop

Whirlpool dishwashers have drain valves with an internal solenoid. This valve opens and closes to drain water out of the tub. If the drain valve is stuck, lubricate the lever, and remove any debris clogging the valve. Remove any objects that are preventing the drain valve from freely opening and closing. If the valve is not working properly, you must replace it. Always install a high drain loop to prevent water from the sink entering your dishwasher. Create a loop of the drainage hose that is at least 18 inches high. Attach this hose beneath a section of cabinetry.

Hi from retired Englishman in SW France,

You have actually posted your Dishwasher problem onto the (garment) Washing machine forum!

However I have checked my Whirlpool list for dishwashers and for some models 'F4' stands for 'drainage' (as you have checked) but for others it mentions (quote) 'no heat, relay, NTC (thermostat), connections, underfilling are all possible'(unquote).

When there is an NTC problem with washing machines we often suggest pouring the contents of a couple of boiling kettles into the washer as it sometimes kicks the NTC into life! Might be worth doing that with your dishwasher before calling for service ;-0)

If this has assisted you please consider a 4 thumbs up for the rating.
Thanks and good luck!

my dishwasher runs through the cycle as normal for 20mins and then starts bleeping nonstop. opening the door the start light flashes without any pauses and the light above prewash is on. my engineer cnat figure this out as the flashing has no pauses. help.

My solution to this problem was to simply unplug the power from the wall for a few seconds...plug back in, try to cycle again and the wash cycle starts fine now. May have been caught in a cycle loop or something. Any way this solution worked for me hope it works for someone else.

Hello, there isnt much that you can do, there could be a number of problems. It could be a slight blockage somewhere from your drainage hoses to your pump. It could also not be spinning properly. If you want to drain the rest of the water out you will need to get your drainage hose and lay it flat on the floor to a drain, this will stop things getting smelly. You just may have to get a repair man in, I hope this helps.

Contact Whirlpool service immediately to get a service call scheduled before the warranty expires.
Most dishwashers that begin taking longer to complete the cycle have a failed heating element but that also normally means that the dishes do not get fully clean and the glassware has a film on it after the cycle ends.
Good Luck!

keep the start button pressed in - the machine will empty out the water and cancel the cycle....then start over again.

Check to see if there is a waste basin at the bottom of your dishwasher. Some models have them and they require regular maintenance / cleaning every 6 months or so. If one does not exist, try to purchase one of the JetDry Dishwasher cleaner and set your dishwasher to run at its hottest (usually "pots and pans" or "extra hot") for about 2 cycles. That should clean the drain of the large food particles that have accumulated in the dishwasher drainage. Should the above not provide satisfactory results, you may want to try a VERY SMALL AMOUNT of drain cleaner in the middle of an empty cycle to try and remove the debris. (CAUTION: too much drain cleaner will damage the waste bin if not rinsed properly and render your dishwasher useless..please only do this at your own risk)
