Miele dishwasher is loved by the user for its efficiency and longevity. This brand of washer has a self-diagnostic mechanism, which helps users diagnose faults know faults within the washer after running a short diagnosis. In most cases, the washer’s self-diagnosis mechanism picks up a fault within the washer, interprets it, and shows it as an error code in its display screen.

What Does F14 Mean On Miele Dishwasher

The F14 error code shows on your washer’s display screen when the washer’s program is interrupted and its drain pump operated. When the circulation pump operates after your washer’s water intake step, the appliances heater pressure switch is examined to ensure the required water pressure is available in the washer’s wash water circuit. For this reason, the washer’s heater relays need to be activated. For this error code to appear on your washer’s display screen, your washer heater switch might have picked insufficient or no water pressure in your wash water circulation pump.

  1. Your Miele dishwasher stops the washing cycle and on checking, you notice no water is getting pumped during the cycle.
  2. The wash arm(s) are not spinning – if the dishwasher circulation pump is clogged, it won’t put out sufficient pressure to rotate the arms.
  3. If the wash motor is good (you can run the diagnostics feature to check if the wash motor is working) and the drain pump works but no water sprays in your dishwasher after filling up, then probably you are looking at a troubled circulation pump.

F14 Miele Error Code – Problems With The Circulation Pump

Circulation Pump Dirty

Before you order a new circulation pump, you need to consider cleaning your current circulation pump because this usually fixes the problem. You need to completley disassemble the circulation pump and take a good look at verything.Once you remove the wire harness clip that gives the entire unit power, the motor unclips behond the impeller and detaches from the entire pump. Once the motor is partially removed, you need to pull rotor out of the plastic barrel. This is the cylinder attatched to the round part that’s attatched to the impeller. You need to clean the entire barrel, shaft and rotor. Then you need to add some lubricant to the movable parts of the pump. Once done, put everything back together and you should find that the circulation pump is working perfectly.

This is the first thing you need to do before you consider buying a new circulation pump. Even though it doesn’t look dirst and it seems like it would work perfectly, cleaning it and adding some lubricant will allow the motor to initiate spinning mcuh easier. If you don’t feel like you cant diassemble the circulation pump, then you can replace it.

Blockage In Circulation Pump

A blockage in the impeller on the ciruclation pump can cause the F14 error. To remove any potential blockages, you need to disconnect your dishwasher from the electric supply and the water supply. Then, turn the machine uoside down and remove the bottom panel. Remove the circulation pump that’s secured by a screw in the back panel. Wiggle the circulation pump away and remove the packaging piece that fits between end of the circulation pump and the dishwasher casing. Locate the ciruclation pump on the bench, remove the 2 screws and prise open the two small clamps to remove the end of the pump. Once removed, clean the end of the impeller and remove any blockages or debris in the ciruclation pump.

Ciruculation Pump Impeller Stuck

If you’ve noticed that the pump is making a humming sound, the impeller may be stuck on something. If this is the case, you need to remove the spray at the bottom then connect a hose to your kitchen faucet. Force water through the hole where the sprayer was attached. Once you do that, you may notice some debris get rinsed out of the pump – and this could have been the issue. Once all of the debris is out, then the pump motor might start to work again. If it was a case of the motor being stuck, the chances of the pump being damaged is low – you simply need to get rid of the stuck debris.

To prevent debris from being stuck in the pump, you need to keep the screens and filters clean. Mineral deposits can buildup which can cause the pump impeller to become stuck, the chances of this happening are also higher if you live in an area with hard water. Removing mineral deposits from the filter and screens that cause the impeller to be stuck can be done with vinegar. You need to soak the inlet to the pump in viegar for a few hours. You can remove the pump using a flat head screw driver and trying to spin it.

Once the inlet to the pump has been soaked in vinegar for at least two hours, check to see if the impeller will start to turn much more easily. You’ll notice that it resists a lot less. Once removed, you need to reinstall it and check if it starts working like new.

Testing If The Circulation Pump Is Damaged

To test if the circulation pump is damaged, you need to dismantle it and test it with a multimeter (view on Amazon). A multimeter will allow you to measure two or more electrical values. This is used to measure voltage (volts), current (amps) and resistance (ohms). The readings you get will allow you to diagnose if there’s a problem with the circulation pump because you can compare it against standards.

You need:

  • Screwdriver
  • Pair of pliers
  • Multimeter

To take out the circulation to test it:

  1. Unplug the dishwasher.
  2. Pull it out.
  3. Lay it on its side.
  4. Remove the dishwasher’s base plate by using your screwdriver to remove its screws first.
  5. Disconnect anti-flood switch connectors and set them aside. Also look for any other connector and disconnect it
  6. Locate the motor and the clamps on the hoses connected to the circulation pump.
  7. Remove the clamps and hoses with the pliers.
  8. Un-couple the ground wire to the pump and disconnect the necessary connectors.
  9. Remove the screw that holds the circulation pump. You’ll find this on the outer side of the circulation pump.
  10. Take the motor out and remove the hoses connecting to the circulation pump. Your pliers will help you do this.
  11. You can now take out the circulation pump.

Test the circulation pump with the multimeter:

  1. Disconnect the motor’s two wire leads from the wiring harness.
  2. Select your multimeter to the ohms setting.
  3. To measure the resistance on the part’s terminals, touch the probes on the terminals and check the reading.
  4. Look for 100 OHMs. If you receive anything considerably lower than this, it needs to be replaced.

Note: While you have access to the motor, check if the motor is seized by inserting the screwdriver into the motor’s spindle slot and trying to rotate it. You should notice that the spindle slot spins freely and if it doesn’t, you need to replce it.

Fixing Miele F14 Dishwahser Error Code

Before you think about getting a new circulation pump, you can try some fixes that’ll clear up the F14 error code.

Inspect your washer’s dispensing of rinse aid and detergent:

  1. Excess foam buildup shows that the pressure at your heater pressure switch will be lowered.
  2. Look for the correct water level in your machine. Ideally, the level of water should be slightly below the filter arm.
  3. Inspect all filters and ensure they are not blocked.
  4. Inspect if your circulation pump is broken by carrying out the following procedure:
  5. Open your dishwasher’s door and put the bypass tool within its latching mechanism.
  6. Switch on your dishwasher and choose the start wash program. Start.
  7. Pay close attention to your washer’s lower spray arm after the thirty-second drain step. The circulation pump needs to be operating as water flows into the cabinet, increasing the pressure of water flow. A small stream of water should ideally be coming out of your lower spray arm.
  8. When water flows out of the spray arm, the washer’s circulation pump operates as expected, and the system has no blockage, press your appliance’s door handle to release the bypass tool from the door lock.
  9. If there is no water, continue with the troubleshooting.

Start the senor wash program:

  1. Start the senor wash program, you should hear the dishwasher draining any water leftover from the previous load.
  2. Wait 10-20 seconds after the machine starts filling again.
  3. Open the door.
  4. Pour 4 litres of cold water in.
  5. Close the door & program continues on automatically.

This fault is caused when the heater pressure switch B1/13 is broken or blocked by foreign objects. Fix it by examining the heater pressure switch. You also need to examine the wiring harness and connection plug. If necessary, replace your heater pressure switch.
