Mitsub U0 E9 Fault

[jwarren]

I have the error code U0 E9 displayed on the remote control - does anyone know what this means - cant find any fault but the indoor fans are only working on low speed even though high spped is selected. The outdoor unit is PU5Y G5A. Anyone got any idea what fault could be ?

Could be a drainage fault...
