Watched the repair video available on the website. VERY HELPFUL. I think I would have been very frustrated without the steps shown in the video and how it showed how to disassemble to get to the diverter valve. My diverter valve was leaking and triggered the error code. The common failure is the o-ring but one I removed the diverter valve, I noticed the leak was from the valve shaft not the o-ring. I replaced the diverter valve with the new one. I ran into difficulty reinstalling the valve. I could not get close to engaging the bayonet mount due to placing the o-ring on the diverter valve assembly. After placing the o-ring on the sump assembly first, the valve reattached easily. Reassembly was easy and without the o-ring difficulty, I would say the dishwasher was back up and running in less than 2 hours.
