E91 Problem Showing E91 Problem

Runyes makes autoclave dental equipment to my knowledge. Not washing machines. The sole Runyes user manual I download does not refer to a e91 error. You may have to contact the company's support. https://livrosdeamor.com.br/download/runyes-autoclave-service-manual-5cc67702784be?hash=fc111deb53f2c65c3f6b4f8892d455d8
