Error code RELAY 1 BROKEN
Appliance Blast Chiller
Quick answer

The electronic board of a U-Line blast chiller detected a failure on relay 1. The manual says to call service.

Model compatibility: U-Line reuses codes across series and model years, so RELAY 1 BROKEN may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

The electronic board detected a failure on relay 1; call service.

A U-Line blast chiller that shows RELAY 1 BROKEN is reporting that its electronic board has detected a failure on relay 1. The alarm comes with one instruction: call service.

Which models show it

The alarm belongs to the touch screen controller used on the UCBF432, UCBF532, UCBF632, UCBF559 and UCBF659. It is a current-generation alarm.

What you can do

Open the ALARM tab on the touch screen to see which alarms were raised during the cycle. Write down the wording as displayed and leave the board work to a technician.
