What E30 actually means
The machine has tried to fill with water and not enough has arrived in the time it allows, so it stops at the start of the cycle.
On Bosch washers this is a water intake fault \u2014 the control board opens the inlet valve, waits for the water level to rise, and if it hasn't within the set time it aborts and shows the code. You'll usually see it within the first minute or two of a programme, with the drum still dry or barely wet. On older Bosch machines built before 2010 the same physical problem showed as F17, F29, E17 or E29.
What usually causes it
- Tap turned off or only part open, or the mains water pressure is low
- Kinked or trapped fill hose behind the machine
- Blocked filter in the inlet hose connection at the tap end
- Faulty water inlet valve not opening when the board tells it to
- Pressure/level sensing fault, so the board never sees the water it has taken in
What you can safely check yourself
Work through these in order. Anything beyond this — panels off, testing parts, anything to do with the wiring — is an engineer's job, and not one to attempt with the machine plugged in.
- Check the water tap feeding the machine is fully open.
- Look behind the machine and make sure the fill hose isn't kinked, crushed or trapped against the wall.
- Run another tap in the house to confirm you have normal water pressure and no supply interruption.
- Turn the machine off at the socket for a minute, then power up and try a short cycle \u2014 this clears the code if the cause was a temporary supply problem.
- Close the door firmly so the catch engages before starting.
When to call someone
This sometimes clears with the checks above. If it comes back, it needs looking at properly. We cover Nottinghamshire, Derbyshire and Leicestershire, and it's £66 including VAT for an engineer to come out and diagnose it — £84 in total if it's repaired on the visit with no parts needed. Any parts needed are quoted on site before we fit them — you decide. Every repair carries a 90-day workmanship guarantee.
Outside our area? The explanation above still stands — take it to a local engineer and tell them the code. Knowing it saves them time and you money.
