I have a Bosch Logixx8 1400 Express washing machine. It has taken to beeping and complaining when part way through a wash or rinse cycle. The error displayed is F:29 which claims to be low water pressure. However the water pressure is fine (checked by the water company) the water filters are clear, and the machine starts to fill with water fine and only complains after a few minutes of operation.

It could be a glitch in the logic card. Try turning off the mains power supply (pull the power plug off the wall). Wait about 5 minutes. Reconnect. This procedure resets the logic card and removes any errors induced.
Good luck!
