AQUA SENSOR BOSCH DISHWASHER NOT FILLING WITH WATER

E15 error code indicates that there is water sitting in the base of the dishwasher.
Most common reasons:

• malfunction of the water drainage sensor when the aqua-stop worked
• the system is clogged

Not enough information to answer. Need manufacturer and model number before we can help.

your dishwasher is leaking water. the bottom or base of the unit is like a big catch pan, the pan has a water sensor witch is two metal contacts positioned just over the bottom of the pan. As water from a leak begins to fill the pan and makes contact with the two metal tabs it opens the circuit to a cut off switch at the water inlet valve. Slide the unit out from the cabinet just far enough to access the sides, about 20 inches, As water is removed from the panand no longer making contact wit the water sensor power will be restored to the inlet valve, Now you begin looking for the source of the leak, You may need to start a wash cycle, this is why the unit needs to remain connected. The source of the leake will dictate what needs to be disconnected and position of the unit. Something like the water level sensor can be replaced without fully uninstalling the unit.

the valve and wiring can be replaced you cannot remove it altogether as it wont be able to fill up, bosch aqua stops are normally powered solenoids that also double as the water inlet valve unlike most other aqua stops

this sounds like flow sensor failure,it it fails machine will either not fill up or fill and drain without washing its a cheap part to replace and is fitted downstream of inlet valve behind l/h/s side panel either attached to inle hose or heat exchanger.

we have a bosch aqua sensor and it doesnt fill with water

as long as it is sealed and you should also make sure there is not water in the white plastic pan under the dishwasher..

create an inverted trap in ther dishwasher drain line so the water cant back feed

Most of the dishwasher has a Thermal hold period in which the machine will not advance to the next cycle until the water temperature reaches a specific degree. it is possible that your aqwa sensor/or heater is bad OR as in most of the cases, the Timer relay that is responsible in turning the heater on is stuck open, in this case you need a new timer. So,Check Timer/Aqua sensor/Heater

f is fill fault to much or not enough water or water in the sump white plastic base the f code will not go away until you solve the problem when the f code shows up the drain motor will run all of the time
