Bosch Dishwasher - w/ error E09 (Glorieta)

Bosch Dishwasher all stainless interior and exterior. It has worked great and had error E09 come up and tripped the breaker. Most likely a problem with the heat pump and it can be fixed. The part costs a lot less than a new washer, but we were ready for an upgrade with newer features. Racks work well, but do have some missing wheels. Approximately 8 years old.
