Dan S Telford , PA September 05, 2020 Dishwasher needed a new roller and spray arm. Replaced both the roller and spray arm when they arrived. Took about 2 minutes and has the dishwasher working like new again. Next purchase might be the bottom rack to replace the original, which is getting rustier by the day.
