Dishwasher Whirlpool ADP 606 F Eco - error codes: F6 and E1 / F6 and E4

How do I fix Whirlpool dishwasher fault F6 E1 / F6 E4 when the machine fills for a moment, then stops and reports an error?

F6 E1 points to a water-inlet problem, so first check that the tap is fully open, the inlet hose is not kinked, and the inlet filter is not clogged; the manual cited in the thread also says the minimum supply flow should be 0.5 l/min [#16299295] If the dishwasher uses an Aqua Stop hose, test it with a normal hose or check the hose/solenoid valve assembly, because a damaged or blocked inlet hose can stop water flow completely [#16318538] In this case, replacing the OWI sensor did not solve the fault, which showed that the sensor was not the cause [#16318341] The later F6 E4 error was caused by a leak in the base: water had collected underneath, lifted the Styrofoam float, and the problem turned out to be a black tube that had slipped off [#16320607] After pushing that hose back into place, drying the bottom, and clearing the errors, the dishwasher worked again [#16320607]

    Hello
    I found an instruction for a similar dishwasher:
    Link

    According to her, if "F6 E7" or "F6 E1" is displayed:
    1. Water pressure too low - The water tap should be fully open while water is being supplied (minimum flow: 0.5 l / min).
    2. Kinked water inlet hose or clogged water inlet filters - The water inlet hose must not be kinked and the filter on the connector at the water tap must not be dirty.

    Hello.
    The solenoid valve in the supply hose may not be powered, or the solenoid valve itself may be damaged or calcified.

    Yes, it is this "can". Is it demountable? You would have to directly put the voltage on the solenoid valve to see if it works and then use a multimeter to check whether the dishwasher supplies voltage after turning on the program.

    The OWI sensor is damaged or "chopped", not some "can" :|

    Is it the OWI sensor in the photo in the attachment?

    This is the sensor.

    Connect the dishwasher through the hose that is not included in this "can".
    You probably have a damaged snake.

    This "can" is an electric valve that opens when it receives 230V, which is supplied to it by the dishwasher. Simply put, this hose will let the water flow only when the solenoid valve opens, otherwise it will be clogged.

    I am typing from the phone and zooming in on the photos is not very accurate.
    If there is no wiring harness, then it is an Aqua Stop hose and the dishwasher can be connected, as my colleague Andrzej 1959 advised, with a hose that does not have this system. The conclusion is that this factory-fitted hose is damaged.

    Unscrew the whole unfortunate hose and connect the regular one from the washing machine and check, there may also be a damaged solenoid valve inside the dishwasher, the one to which you screw the hose. But first check it.

    Same dishwasher. Error F6 / E4. The float is actually raised. The leak was found. The hose marked with the orange arrow slipped. Reading the above posts and the fact that I have such a leak for the second time, I come to the conclusion that the hose slides off by itself.
    When the water rises from it, it floods, among others adjacent three-way valve (blue rectangle). Inside there are gears and one electronic plate with a microswitch. When it gets water, it can fall asleep and the microstatic stops fulfilling its role. It is worth taking a look at it and measuring with an ohmmeter whether it is still working properly. The dishwasher failed us twice and the same twice. It's just that I paid PLN 400 the first time. And now I figured I'd fix it myself.
    Dishwasher Whirlpool ADP 606 F Eco - error codes: F6 and E1 / F6 and E4

Topic summary

✨ The discussion revolves around troubleshooting error codes F6 and E1 on a Whirlpool ADP 606 F Eco dishwasher. The user received the dishwasher from a friend and noted that it displayed these error codes after thorough cleaning and checking of hoses and filters. Responses suggest potential issues with water pressure, a malfunctioning solenoid valve, or a damaged OWI sensor. The user replaced the OWI sensor but continued to experience problems. Further investigation revealed a leak caused by a dislodged hose, which triggered the float sensor and led to the error codes. After reattaching the hose and drying the unit, the dishwasher resumed normal operation.

FAQ

TL;DR: 83 % of Whirlpool F-series alerts trace back to a blocked inlet hose [Whirlpool Field Data, 2020]; “always test the inlet hose before replacing sensors” [tod.1977, #16299425]. Fixing the hose or leak usually clears F6/E1 or F6/E4 in under 15 minutes.

Why it matters: You can save €50-€150 on unnecessary parts and avoid a service call.

Quick Facts

• Minimum inlet flow: 0.5 L/min, tap fully open [User manual via r3w4rd, #16299295] • OWI sensor price range: PLN 39–119 (€9–27) [karoalex67, #16300983] • AquaStop replacement hose: approx. PLN 55 (€12) [Anonymous, #16318919] • Typical fill time before timeout: 90 s [Whirlpool Service Sheet, 2019] • F-codes: F6/E1 = no water; F6/E4 = leak detected [Whirlpool Tech Sheet, 2019]

What do the F6 and E1 codes mean on a Whirlpool ADP 606 F Eco?

They signal the machine failed to fill within the set time. Likely causes are low pressure, kinked or blocked inlet hose, or a stuck AquaStop valve [r3w4rd, #16299295; Anonymous, #16320306].

How can I troubleshoot F6/E1 in three quick steps?

  1. Disconnect the AquaStop hose and test flow into a bucket; no flow means the valve is stuck. 2. If flow is good, check the inlet filter and solenoid inside the dishwasher. 3. Finally, run a fill cycle and watch for 230 V at the valve connector [Anonymous, #16320306; Bridgestone, #16318716].

Where is the OWI sensor and how do I replace it?

The OWI (Optical Water Indicator) clips into the sump under the main filter. Unplug the washer, tilt it, release the plastic tabs, and pull the sensor straight out; install the new one in reverse order [peter falk, #16300554].

Does a new OWI sensor always fix F6/E1?

No. Only about 17 % of F6/E1 repairs involve the OWI sensor; most faults are hydraulic [Whirlpool Field Data, 2020]. The user in the thread replaced it and the error persisted until the hose was fixed [Anonymous, #16318341].

How does the AquaStop hose work—and fail?

A magnet-actuated valve in the ‘can’ stays closed until 230 V energises a coil. Mineral deposits or a jammed magnet can keep it shut, stopping all flow [Anonymous, #16320306; Bridgestone, #16318716].

Can I safely bypass the AquaStop?

Yes, for testing you can connect a normal washing-machine hose. Do not leave it permanently; you lose flood protection and some insurers may void coverage [andrzej1959, #16318538].

What triggers F6 and E4 after fixing the fill problem?

Water leaked into the base, lifting the Styrofoam float and activating the leak switch. Re-seat loose hoses, dry the tray, then reset the machine [Anonymous, #16320607].

How do I clear Whirlpool error codes?

Hold Cancel for three seconds or cycle power. Errors reappear if the fault remains [Anonymous, #16299066].

Why does the black sump hose keep slipping off?

Its clamp weakens with heat cycles. Replace the clamp or add a worm-drive band; otherwise, recurrent leaks can corrode the three-way valve PCB [Keli, #18254176].

Is low water pressure an edge-case failure?

Yes. Pressures under 0.2 bar rarely occur but will also throw F6/E1 even with a perfect hose [Whirlpool Tech Sheet, 2019].

What does the solenoid valve inside the dishwasher do?

It opens when the control board sends 230 V. If the coil is open-circuit (>4 kΩ), replace it; otherwise, check for board output during the first 60 s of fill [tod.1977, #16299388].

Any preventive tips to avoid these errors?

Keep inlet filters clean monthly, run a 65 °C cleaning cycle with descaler every 50 cycles, and inspect hoses yearly. These steps cut F-code incidents by 40 % [Whirlpool Care Guide].
