Strong bad smell from inside the Hoonved dishwasher, especially when opening the door after it has been idle.

Safety first: Turn off power before deep cleaning. Use appropriate PPE when using cleaning chemicals.

• Clean filters and sump: Remove all filters and clean thoroughly. Scoop out any sludge or debris from the sump.
• Run cleaning cycle: Use a commercial dishwasher cleaner or descaler approved for Hoonved machines. Run a hot cleaning cycle without dishes.
• Check drain function: Ensure the machine drains completely at the end of cycles. Fix any drain issues to prevent standing water.
• Regular maintenance: Implement a daily and weekly cleaning schedule for filters, tank, and spray arms to prevent odor recurrence.
