Water filling does not stop

The water level in the dishwasher (ancient Indesit 310) does not activate the pressure switch. Pressure switch is ok and no leaks on any hoses. The water level in the hose leading on to the pressure switch remains constant, although the level in the dishwasher keeps on rising (this hose is still intact). Any solutions?

Re: Water filling does not stop

Water supply to the dishwasher is done through an electromagnet valve,loocated at the water pipe's enterance to the machine. A defect in the valve may mean that it's no longer able to shut off completely when the electricity has been turned off to it, and the valve may leak and drip water into the tub.You can easyly open the valve and clean it (from scale or other dirt). Be aware you should disconnect the power cable from the machine before doing it !!!!! and as well to close water main tap to the machine. In case cleaning doesn't help, you should replace the valve. Good luck !!

Water level in DI450, how to set the level control switch?

25 years ago technicians repaired the pressure switch if it was possible.
Today, their price is such that it is not worth and it is very small chance that you will succeed. My advice is to buy a new pressure switch and replace it.

If you only intersted to look inside, see the following link:

if you just want to try to fix the pressure switch then follow this link:

Dishwasher overfills?

the water level sensor is disconnected but probably bad and needs to be replaced. This is possible to be done by you but I like when they do it, any thing happens you have there insurance to make repairs and be responsible for property damage.

Bosch shx46l15uc water not heating


Water not heating can be a few reasons on these. The water heater for one. Possibly the temp sensor or NTC. These also have a pressure switch on the back of the water heaters so the power to the element will only switch on when sufficient water is pumped through it. This could be an issue.

Another thing is to check the water level. Once the dishwasher has filled and pumps normally (about 5 min into a cycle), open the door (watch for splashes) and check the water level. Is should sit above the metal water filter grill by about 3-4 cm. If the water level is sitting just at the level of the filter grill or lower then the problem could be the inlet fill time. There is a pressure chamber on the left hand side with a microswitch activate by a diaphragm once the water level has been reached. It could be this switch is faulty or the diaphragm is stuck in the 'filled' position activating the switch. This would mean the actual fill time would reduce significantly with barely any water going into the unit.

Please be careful if checking any electrical components that the power is off and unplugged. Only if you are technically competent should you attempt live testing of any kind.

Aeg slimline dishwasher 64800. AL5 alarm, but fills up

This control procedure is in operation only during the cold wash and heating phases.
  • Once the pressure switch has closed in the "full" position, it must remain "full" until the subsequent drain phase; if the pressure switch signals "empty", the fill solenoid is activated for a period equivalent to the period of aperture of the pressure switch.
  • The maximum aperture time for the pressure switch (T) during the entire phase is 60 seconds; if this period is exceeded, an alarm condition is generated.
Alarm: AL5

Possible causes:
  1. Dishes upside down
  2. Central filter clogged
  3. Siphon effect created in drain hose
  4. Leakage in sump - pressure switch tube.

Water wont stop filling up

If water keeps filling or dribbling into the machine with the power off it's the water inlet solenoid. If it overfills only during the cycle then it is the pressure switch or pressure switch tube.

The water level detector pipe could be obstructed / blocked. This thin plastic pipe is at the bottom of the washer and as it fills to the correct level of water the pressure in the pipe activates a water level switch in the washer. Sometimes the air pressure pipe becomes blocked / obstructed or the contacts of the pressure switch become burnt. You can disconnect the pipe and blow through it and the pressure switch is normally factory set and does not need adjusting. Replace it if necessary.

Water doesn't fill to capacity

Washers have a water level sensor that consists of a plastic pipe that feeds a pressure switch that activates once the correct amount of water causes the air pressure in the pipe to activate the water level switch. The switch is normally adjustable but should be factory set only once. The plastic pipe does sometimes become clogged and could be cleaned.
I have found that in some instances the electrical contacts in the pressure switch burn and the pressure switch must be replaced.

Bosch SMS4012GB dishwasher. Refused to fill. Found tray full of water in base of unit. Mopped up water about 2 litres. Machine works but lower reservoir on the side of the machine with float switch...

An electric switch activated by air pressure. This device detects air pressure exerted on it through a flexible tube connecting it to part of a water tub.
When activated, this switch then opens an electrical circuit stopping further filling of water into the machine.. May also be called a PRESSURE SWITCH. if not activated definately it will cause overflow.

Check the wire harness to the pressure switch. or tap your float switch with finger tips may be it get stacked. if nothin happen replace the pressure switch.
Rate my solution if useful.

Indesit dishwasher overfilling

There are two ways that dishwashers generally fill. One is a float inside the tub, the second is a tube which fills with water, loops and goes to a pressure switch below the machine. That switch is usually about 1.5 inches in diameter, two wires and a small hose going to it. The float witch is found below the float in the motor area. With the float, sometimes they jam with too much old detergent or food goo. Clean out. Both can have the switch weld closed. Change the switch in either case. Since the unit is not filling with the power off, I'm going to guess the water solenoid is okay.

If it does not fill properly to a certain level, the heater will NOT come on, so you need to solve the filling problem. Is the drain hose raised sufficiently? Is the pressure hose blocked? Does it let water in and then just stop? Oshie
