No water flow into machine - Maytag 24 in. MDB3700 Built-in Dishwasher

The water flow error and ST-Boiler error on your Schaerer Coffee Soul 10 may be caused by a variety of issues related to the machine's water flow system or electronics.

One possibility is a blockage or restriction in the machine's water line. The water line can become clogged with debris, which can restrict the flow of water and cause the water flow error.

You mentioned that you cleaned the blockage where the water line connects to the machine, but it's possible that there may be additional blockages further in the water line or in the machine's internal components.

Another potential cause of the error is a malfunctioning level probe in the steam boiler. The level probe is responsible for measuring the water level in the boiler and controlling the heating element.

If the probe is malfunctioning or the connection is loose, it can cause the ST-Boiler error and the water flow error. The level probe and its connections should be checked to ensure that they are securely attached and functioning properly.

Other possible causes of the issue could include a malfunctioning solenoid valve, a defective flow meter, or a damaged pressure switch. These components all play a role in the machine's water flow system and can cause the water flow error if they are not functioning properly.
It's recommended to contact a qualified technician to diagnose and repair the issue if you are unable to identify the source of the problem or if the issue persists after troubleshooting. They can use specialized tools and knowledge to diagnose and repair the issue to get your machine back up and running properly.

There are a few other potential causes for slow water flow in a washing machine:

1. Clogged or partially clogged water inlet valve: The water inlet valve is responsible for controlling the flow of water into the washing machine. If it is clogged or partially clogged, it can cause a reduction in water flow.
2. Washing machine pump: The pump is responsible for moving water through the washing machine. If it is damaged or not functioning properly, it can cause a reduction in water flow.
3. Water supply hose: The hose that supplies water to the washing machine may be clogged or damaged, which could cause a reduction in water flow.
4. The washing machine itself: There could be an issue with the internal components of the washing machine that is causing the slow water flow.

If you have checked the filters, water pressure, and solenoid and they are all functioning properly, you may want to try checking the water inlet valve, pump, water supply hose, and the washing machine itself for any issues that could be causing the slow water flow.

check flow from the supply tap ( washer expanded and blocking water flow )
check gauze filter at hose end at machine
check water solenoid for full flow ( diaphragm stopping full flow)

Sounds like a bad shutoff solenoid. It operates the valve to let water in and then shut it off. There should be a valve behind the machine where the hose connects to the wall so you don't have to isolate hot water to the entire house.

Put the temp select switch on HOT, start machine. If water comes out check the flow amount. If no water flow, replace inlet water valve. If there is water flow switch to COLD, start machine. If water comes out check the flow amount should be approximately equal or slightly more than flow on HOT. If no water flow, replace inlet water valve. Move selector to WARM, start machine. Now there should be twice the flow of water than there was with HOT and COLD temps. I suspect it is the HOT side of inlet water valve that has failed because machines usually rinse with COLD water.

Take the cup warmer off the top and find where the water line comes into the machine, follow this line to a tap that has a screw in knob. If you turn the know clockwise it will slow the flow of water to the hot water spigot.

HI
Its your flow meter. If you have a restriction in the intake line the message will not go away. There is a flow meter inside the machine that measures water flow. If the flow meter does not spin when the pump is running, the computer thinks that the pump is not primed. Coffee grounds will get into the intake and restrict the flow meter. If you get a restriction in the water intake (below the water tank, on the machine) the pump may run and water comes out, but the flow meter does not create the jet of water to spin the turbine wheel to send impulses to the computer. You get the ventilate message.
You need to take the flow meter apart and clean it or replace it.

disconnect your hoses and check for pressure without connected o machine, then check with int he water inlet valce for a clogged screeen slowing the pressure

TRY CHANGING THE COLD WATER TAP IN THE MACHINE.

Hi,

You need to replace the printed circuit card in the machine.
