What is Philips CT error code WR?

Water Required alarm on the Oxford 2195 cooler cabinet. It is reported by the Oxford 2195 Cooler Cabinet (MRI gradient/primary water cooling) on Eclipse 1.5T and Polaris and Apollo CT systems. Severity: Alarm (low) — coolant top-up required; subsystem: Water Cooling System (Oxford 2195 Cooler Cabinet).

What should a field engineer do about WR?

Water Required indicates the pump/controller has detected that additional water is needed. Follow the commissioning fill procedure: fill the header tank with distilled water via the rear filling cap until the level indicator lamp goes off, without overfilling.. Isolate the Water Cooling System (Oxford 2195 Cooler Cabinet) subsystem and follow the status-code troubleshooting in the service manual. FSELIB documents the full diagnosis and remedy for the Eclipse 1.5T / Polaris / Apollo.
