Hi, Looks like common fault but cant find solution. Indesit WD143 errored out early on in cycle making constant pump draining noises. Cleared 5p from pump which may have been the issue. Checked all other hoses/pump impellor and all OK, cant see any blockages. Machine now drained but can't reset it - tried moving dial to the dot and switching off when neon flashed quickly, then selected new program but no avail. The error code is 10 flashes. Any idea what this one means? When it restarts theres small knocking sound from top somewhere, and then the clicking round starts again.
