Hi @timgrose
Does the washer spin if you manually rotate the cycle timer to either the drain/spin or rinse/spin positions?
The cycle timer is incorporated in the electronic control board so hopefully that's not the problem
Here's the [document|32626|tech sheet] for the washer that may help to find out what's happening.
Go to p.2 to view the ''Activating the service diagnostic test modes'' procedure and check if any error codes are being shown by the status lights when the diagnostic tests are being run. If there are any errors, see the ''Fault/Error Code Display Method'' chart on p.3 for how to interpret the lights to know what the error code is.
The error codes, their meaning and possible causes are shown on p.6→p.7.
If you find the problem and it's a faulty part that needs replacing, here's the [https://www.searspartsdirect.com/model/tt7fut67yf-000582/kenmore-1105142510-washer-parts|parts list] that is useful.
Locate the wanted part in the list and note the part number that is shown with it. Search online for the ''part number only'' to find suppliers that suit you best.
If you search on YouTube for ''(insert wanted part number) replacement'', sometimes if you're lucky you'll find videos that show how to remove/replace the part.
