Dishwasher comes on but No water starts filling up. Can it be a Switch or water intake pump?

Probably jug impellor part number (424099) from espares, buyspares or bosch direct.
No fix unfortunately, this problem manifests as unit starts to fill and motor does not switch on. Eventually the unit overfills and the pump and fill start to alternate and check water light comes on. If this is the fault then this part is the solution it runs in line with the inlet valve and side fill chamber, take the left side panel off (looking from the front) it is tucked away behind the hoses bottom left (white plastic disc with two wire connection tag). Check water light can also come on if the unit is not pumping, if this is the case, repost and I will try and talk you through clearing this fault.

when you start a cycle, your machine should drain for 30 sec, fill with water, and then the circulation pump should come on. your water level should be up to the handle on the filter in the bottom. if you drain, and fill to the handle and then the intake drain error comes on, your circulation pump is stuck. if it does not fill to the handle, you may have a problem with the inlet valve.

Water Not Flowing Properly

Check to see if the water source to your dishwasher is turned on and not blocked or clogged. Also make sure the water line between the dishwasher and water source is connected and free from blockage. The door has to be closed properly as well.

If your water pressure is low, you can adjust the water intake value on the dishwasher to allow more water to flow through.

There is an overflow detection device on the dishwasher, so if the machine detected that, it will shut down the intake pump and open the drain pump. If this is the case, you will need to call for service because if there is water in the machine it will have to be cleaned out. Remember to turn off the water source to prevent further damage.

Hello

Investigate these five areas if your dishwasher won't fill with water:

As water is filling your dishwasher, a float rises along with it. When the float reaches a predetermined level, it shuts off the flow of water, thereby preventing a leak. Sometimes the float can get stuck in the wrong position in your dishwasher, and it can prevent your dishwasher from filling. Check your float assembly. Replace it if you need to.

The water that fills your dishwasher lifts the float, and when it reaches a certain level, it acts as a trigger for the float switch. The float triggers the float switch to shut off, thereby shutting off the flow of water into the dishwasher. A defective switch may interfere with your dishwasher's filling ability.

Your dishwasher may not be filling with water simply because the water valve's filter screens are dirty and debris-filled. Gain access to your water inlet valve and try cleaning it out. This might be enough to solve the problem. You can learn how to access your water inlet valve in the replace a dishwasher water inlet valve section.

Alternatively, your water inlet valve could be defective altogether. That could be the reason your dishwasher is not filling. Test it for continuity. If it is not functioning as it should, replace it.

Your dishwasher's drain valve is regulated by a drain solenoid. If the solenoid is malfunctioning, it may not allow the drain valve to funtion properly, which in turn could be the reason your dishwasher is not filling with water. Investigate your drain valve and test the solenoid. If the solenoid is faulty, replace it.

Check for a float switch that senses the water level. It may have two level sense of filled and overfill the latter would trigger the waste pump to avoid a flood. If the filled switch has failed, that could cause the problem. The waste pump MAY also be triggered on the basis of the filling taking too much time before the filled switch actuates... if it has failed, the time would be exceeded.

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.

Hi dear.If you are handy enough,that's what you can check to make a solution for yourself.Goodluck.
Check all hoses, connections and threaded unions for leaks.
Note:
If the leak source has not yet been detected, check the following areas
in the toekick and the drip pan for wear and tear:
�� Connection between the circulation pump and the sump
�� Axial face seal of the circulation pump
�� Connection between the drain pump and the sump
�� Connection between the salt container and the water intake
�� Connection between the water intake and the cabinet side wall
�� Overflow (e.g., excess foam formation)
�� Water level between the overflows (�� seating of the lower door seal?)
�� Connection between the cabinet and the salt container
�� Non-return valve in the sump (�� water running back from the drain hose?)
3. Check overflow float switch B8/3 for continuity and correct operation.
4. Carefully dry all electrical components in the drip pan area.
Cause:
Float switch defective.
Remedy:
Replace overflow float switch B8/3.
I hope that helps.Thanks.

Reset the program by holding down the start button. It will be blinking. Then try the same wash selection and start it. If you wired correctly the drain pump will run 30 seconds. If the intake light comes on in 5 seconds and the drain pump is still running then you have a leak. Miele dishwashers have a safety system that catches water and triggers the alert. Ifthis is the case, there's nothing you can do but get a repair person to pull the machine out and find the leak. If the pump does drain only 30 seconds, then it will stop the pump and let water in. If it fills okay then it will circulate the water and if you haven't oversudsed it [ Energy Star machines use much less water and therefore make much more suds if you fill up the dispenser too high with detergent ] the suds will not trip the pressure switch. Otherwise it will start to heat the water. If the intake light comes on again it's important to know when it does. The computer inside evaluates 100's of steps. The Techs at Miele will need to run it with you on the phone. They have scripted access to the electronic memory and you participate to find the information. They can determine if you can fix it or not.

If you have to bang the float to stop the the float switch is not working correctly.. you may have somthing holdig it up or the switch itshelf is failed...

this can happen after inactivity. the circulation pump seal sticks and wont turn . when the dishwasher starts to fill the circulation pump is pulsed on to see if the preasure switch switches over (to see if water is getting into the dishwasher) if the pump does not turn there is no preasure and the machine stops thinking no water has entered. turn pump by hand to cure.
