I have the error 5 coming up erroneously with my S6. Error 5 is claiming that the filter is either wet or blocked asking me to check the filter and brush before randomly reducing the cleaning speed and then stopping. I have cleaned the bearings and brush to ensure there are no obstructions. I have bought a new filter and the error keeps on occurring claiming that the filter is blocked and wet. This then causes the product to stop mid cycle. I also checked and the 'carpet boost' setting was on. Can I get help to troubleshoot this error?
