Whirlpool dishwasher

23 days ago

Sorry if this is a repeat post, wasn't logged in, got hit with reset this and that, so no idea if I'll get notifications on the original.

OK, WP dishwasher, running dry. No water is coming into the dishwasher, but there is a pressurized water supply to the water inlet. I took apart all of the common places that there would be clogs, they are all clean. I replaced the Water Inlet valve (https://www.amazon.com/sk=dishwasher+water+inlet+valve&i=tools&crid=1W76YCPREYWBB&sprefix=dishwasher+water+inlet+valve+%2Ctools%2C168&ref=nb_sb_noss). This didn't work so I took the old one and applied 120V to it and it is changing state, kept the original one.

Any help or suggestions would be greatly appreciated!

The float switch is often at the lower right. After you find it, check for debris blocking or interfering. You can check to see if it works with an ohm meter. Try unplugging the unit for 10 minutes.

Find out if your model has a diagnostic mode you can run. I asked GROK and got this.-

To activate the diagnostic mode for the Whirlpool WDF540PADM1 dishwasher, follow these steps. The diagnostic mode helps identify error codes and test components, which can pinpoint why the dishwasher isn’t filling. The exact sequence may vary slightly depending on the control panel configuration, but the following is the standard method for this model.

Steps to Activate Diagnostic Mode

Prepare the Dishwasher:

Ensure the dishwasher is powered on and the door is closed.
Cancel any active cycles by pressing the CANCEL or DRAIN button, if available, and wait for the dishwasher to reset (lights may stop flashing).

Enter the Key Sequence:

With the door closed, press the following buttons in this order within 8 seconds: Heated Dry → Normal → Heated Dry → Normal
Alternatively, some Whirlpool models use: Any Button 1 → Any Button 2 → Any Button 3 → Any Button 1 → Any Button 2 → Any Button 3 (Choose three different buttons, e.g., Normal → Wash → Cancel, and repeat the sequence.)
Press each button firmly but quickly, pausing briefly (about 1 second) between presses.

Confirm Diagnostic Mode:

If successful, the dishwasher’s control panel lights will start flashing in a specific pattern, or all lights may illuminate briefly.
The dishwasher may begin running a diagnostic cycle, testing components like the water inlet valve, pump, and sensors. This cycle typically lasts 5–10 minutes.

Observe Error Codes:

During or after the diagnostic cycle, the control panel may display error codes via blinking lights or numeric codes (e.g., on a digital display, if present).
Note the pattern of blinks or numbers. For example, a code like F6-E1 might indicate a water fill issue.
Refer to the dishwasher’s tech sheet (often taped inside the kickplate or behind the control panel) for a list of error codes and their meanings.

Exit Diagnostic Mode:

To exit, press CANCEL or open the door. Alternatively, unplug the dishwasher or wait for the cycle to complete.
If no action is taken, the dishwasher may automatically exit after the diagnostic cycle.

Tips and Notes

Locate the Tech Sheet: If you can’t find the tech sheet, error code lists for Whirlpool dishwashers are available online (e.g., on RepairClinic or AppliancePartsPros). Common codes for no-fill issues include:
- F6-E1 or 6-1: No water detected (float switch or inlet valve issue).
- F8-E1 or 8-1: Slow fill or no fill (valve or pressure issue).
Control Panel Variations: The WDF540PADM1 typically has a front control panel with buttons like Normal, Heavy, Heated Dry, etc. If the above sequence doesn’t work, try a variation like Normal → Cancel → Normal → Cancel or consult the user manual.
Safety: Unplug the dishwasher before accessing the tech sheet or internal components to avoid electrical shock.
If It Fails: If the sequence doesn’t activate diagnostic mode, the control board may be faulty, or the button sequence may differ. Contact Whirlpool support (1-800-253-1301) or a technician for model-specific guidance.

Does it run through the complete washer drain and rinse at every choice level and never allow water to be introduced? If you manually add water, will it pump that out?

Check for voltage at the valve when the machine is supposed to be filling. If none, then the control board may be bad.

You may be able to find a Tech Sheet with diagnostic info at ServiceMatters dot com (Limited Access Guest Portal doesn't require a servicer account / log-in). Search by the FULL model number from the tag on the machine.

Hello folks, and THANK YOU for replying.

This is what I did: I put about two gallons in there and started it. The water in the unit seemed to circulate, and get pumped out. The unit seemed to be operating normally- hard to say exactly, but the machine seemed happy. It switched modes a few times. I let it run until it seemed to want more water and was struggling, so thats where I shut it off and came back to report to you guys! Any further thoughts?

There are multiple fills and drains through the course of a complete dishwasher cycle. Possible prewash and/or prerinse, main wash, typically two after-rinses, three in some instances. The number of wash and rinse periods varies per which cycle selection.

Water that you pour in manually before starting will circulate for whatever is the first spray period, then drain. If the inlet valve is bad, or the control board is bad not sending current to the valve, there would be no more water for the remaining spray periods.

Note that there usually is an overfill float that electrically interrupts power to the inlet valve as protection primarily in case of failure to drain so subsequent fill(s) don't overflow the tub. The design/function of the float varies from model-to-model and brand-to-brand, it could also turn on the drain pump in an instance of the fill valve hanging open. Check that your float isn't stuck in flood position.

Just to say, the first rule of asking for appliance help is citing the brand and model of the machine. Not doing so is like calling an auto repair shop and answering "it's white" when asked what is the make/model. That's what an acquaintance once did upon approaching me at the local grocery store to ask about a washing machine problem. I said that I don't expect you to know the model number but can you tell me the brand? She pondered for a moment, said "it's white."

I expect you guys will all get this. Thank you! So simple! The float switch was "stuck". I pulled it out, put it back in, and as I did, I said to myself....."FIXED, thanks guys!". I mean, I haven't run a full cycle and will soon, but I did turn it on and had water coming into the tub instead of hearing the nasty sound of no water.

A sincere thank you. So good. I haven't used this website in years and it is still as good as it ever was!
