What Does Error Code H20 Mean?

The Hotpoint H20 error code signals a water-related issue, meaning the machine isn’t getting enough water, is draining too slowly, or has a sensor fault, often due to closed taps, kinked hoses, blocked filters, or a faulty pressure switch, requiring you to check the water supply, hoses, filters, and pressure sensor.

Common Causes and Solutions

Water Supply

Ensure both hot and cold water taps are fully open and the supply hoses aren’t kinked or crushed.

Inlet Filters

Check the small filters where the hoses connect to the machine and the tap for blockages from limescale or debris.

Drainage

Clear the drain pump filter (usually at the bottom front) and check the drain hose for clogs or kinks.

Pressure Switch/Hose

A small black hose connected to the pressure switch can get a pinhole leak or become blocked, tricking the machine into thinking it’s full or empty; inspect and repair/replace it if damaged.

Door Latch

Make sure the door is securely closed and latched.

Loading

Overloading the machine can sometimes trigger this error.
