Nope.
Flow meter is embedded in the water matrix, left hand side at the bottom. Normal fault is bad connection.
Water indicator is under the mesh filter, in the bowl area at 3 o’clock position.
F7 can be one of several possibilities, check the known fault codes for full info.
If it works when it’s pulled out but fails when it’s pushed back into place I’d suspect the fill hose is being kinked, thereby cutting the water supply either partially or completely.
