Bosch WFK2401UC recently started hanging up showing trouble code "01". I cleaned the filters at the tap and machine ends; did not help. Suggestions?

SOURCE: fault code 01

this is actually a fault code error code 1 not one minute check your manual as codes different on some machines from memory i think 1 is a filling fault this machine uses fuzzy logic if water fill takes longer than 4 mins (low pressure) machine stops can be restarted by pressing start button.
see if machine will complete just a rinse cycle.

good luck

please do a hard reset by leaving the unit plugged off from wall power for one night.

SOURCE: Neff W4380X is showing error code 01

error code 1 is usually not heating it will progress through rinse as heat is not called for, when moves to heat stage will stop at that point inexpensive part to replace.

SOURCE: Bosch WAY32540AU showing LOW WATER PRESSURE but pressure and taps are fine. All filters are clean.

Not sure how you can measure the pressure in the machine, but I think you did. When you did and the pressure in the machine is good, the sensor must be defect. BUT. if you did not measure the pressure in the machine, you should check if nothing is wrong with the water filter on the beginning of the water hose (closest to the tap) and you should check the hose is not bent and nothing is on it, throttling the free water flow.
