Check the inlet screen to the water circulating pump and the water heater element for lime buildup. I've seen a heater element that had a 1/4" thick layer of lime encasing it. The inlet also had some lime and other debris clogging the screen. After carefully chipping away as much as was practical and running lime remover (such as CLR) through the machine, it heated the water much more quickly and had an effective spray.

To prevent a recurrence of this problem, make sure you have a functional water softener ahead of the water heater feeding the machine.

If water keeps running even if the unit is unplugged than the water solenoid valve has become defective.


if the water stops when power is off than there is a problem with either the timer or the fill switch. My bet is on the timer.

Always be careful when opening the top cover. you will be exposing wires. power must be turned off at the breaker or the unit unplugged.

F14 - "level/pressure switch failure." The level switch monitors the dishwasher's water pressure, as it circulates, which is especially critical, during the heating cycle (main wash). Level switch failure can commonly happen from poor circulation, or from the defective level switch, itself. The most common reason for poor circulation is low water fill level. In other words, during the water intake cycle, insufficient water came into the dishwasher. Observe if enough water did come into the dishwasher, Check the water level, by using the filter's handle (located on the floor, of the inside of the dishwasher) as a reference point. At the end of the water fill stage, the water level should be just underneath the filter's handle. If the water level is more than half an inch, below the filter's handle... then that could be a problem. The sympton would be a noisy, sluggish, whooshing sound of water, during circulation - It wouldn't be the same old quiet Miele dishwasher you knew.

If you have the low water fill problem, then look at the dishwasher's water intake hose. Miele call this their Waterproof System hose (WPS). It's a water hose with an integrated electric valve. First, shut your water valve that connects to this WPS; disconnect the WPS from your valve; look inside the end of the WPS. With a needle nose plier, remove the rubber seal, filter and the water restrictor; clean them of any possible debris; put all the parts back into the WPS, securely; reconnect the hose; open your water valve; and test the dishwasher. If the problem persists, then the WPS will need to be replaced (WPS~$170).

Other causes for F14, can be weak circulation from foreign item(s) (plastic wrapping, broken glass, etc,...) lodged inside circulation pump impeller, or no circulation, at all (circulation pump stuck). Of couse, the defective level switch, itself, can cause the F14, too. The least common causes for the F14 can be broken wires to and from, level switch and electronic unit, and a defective electronic unit.

This fault is low pump pressure. more than likely you have some foreign particles jammed in the circulation pump. you would have to remove the unit, tip it on its side and remove the bottom plate and remove the circulation pump and clear the blockage. the unit will start and stop and not work until the pump is clear.

F14 should be heater pressure switch fault - you pretty much have to call a service tech for this one.

F14 is a an error code that means the unit doesn't think it's filling up with enough water because the heater switch isn't being depressed.
When the error happens look inside the unit and look at the water level compared to the filter handle. It should be just below the filter handle touching the bottom of the handle.
If it's lower than that, you may have a bad water valve or bad water pressure from your house.
If the water level is correct, then you have a big issue because either your circulation pump is creating enough force to activate you heater level switch, or your heater level switch is defective and the part will need to be replaced.

Bosch has a safety float switch under the dishwasher basin. If water leaks into this area, the float rises and turns on the drain pump to clear out the water in the dishwasher. Hope I explained that ok :)
Anyways, usually a leak somewhere causes this and unless the leak is fixed and water is removed or evaporates, the dishwasher will remain in the drain cycle.
