Dishwasher displays H35 and stops, often with water remaining

Safety first: Disconnect power and turn off water supply.

• Thoroughly clean filters and sump: Remove all filters and clean them. Reach into the sump and remove any debris or grease buildup.
• Clean side water channels: Remove the left side panel and inspect the transparent water matrix for heavy scale or sludge. Flush with warm water and a descaling solution if necessary.
• Descale dishwasher: Run an empty hot cycle with a dishwasher descaler to improve internal water flow.
• Inspect circulation pump: Access the pump from the base and check for worn or damaged impeller blades.

If H35 continues, the circulation pump may not be generating sufficient pressure and should be replaced.
