We really cannot estimate the cost of your repairs without inspecting your machine. So many different things could be causing your problem, it's not really fair to you -- or to us -- to quote you a price. In general, we can provide you with a rough idea of the cost of parts and labor, but it is just a "guesstimate."
Keep in mind, when we do inspect a cleaner that's not covered under warranty, we provide an accurate, written estimate for you to approve before we make any repairs. If you choose not to make the repairs, you only owe the bench fee for our inspection. We can return your unit to you (at your cost if shipping is necessary), or we can dispose of your unit for you.
