Parts for Thermador MES301HS/01: Control Assy Parts

This replacement tank is the appliance's sealed reservoir. It stores and routes water within the unit's system, helping restore proper flow and preventing leaks when the original tank is cracked, brittle, or contaminated.

• Holds and directs water through the appliance's water path
• Maintains a sealed connection between inlet tubing and downstream components
• Damage or cracking can lead to internal leaks or pooling
• Restrictions can cause weak or no water flow from the system

• Disconnect power and shut off the water supply before starting
• Keep towels handy; some residual water will drain when lines are opened
• Note hose routing and fitting locations; take photos for reference
• Transfer any reusable clips, seals, or brackets from the old tank if needed
• Restore water and power, then flush the line and check all joints for leaks

This electronic control module manages appliance functions and user-interface signals so your appliance runs the selected cycles and responds to commands. It replaces a failed board to restore normal control operation. What it does:

• Receives input from the control panel and sends signals to motors, valves, and heaters
• Coordinates cycle timing and sequencing for normal operation
• Common symptom: unresponsive controls, error codes, or interrupted cycles

• Disconnect power to the appliance before starting any work
• Handle the board carefully and avoid touching circuit traces or components
• Reconnect all wiring harnesses in their original positions and secure mounting hardware

This electronic control board is the main control module that manages your appliance's functions, cycles and user interface. Replacing a faulty board restores reliable operation and control communication between the console and components. What it does:

• Provides power and logic to the appliance's controls, timers and relays
• Interprets user inputs and starts/stops cycles per selected settings
• Sends and receives signals to motors, valves and sensors to coordinate operation
• Can cause unresponsive controls, no power to functions, or erratic cycling when failed

• Disconnect all power to the appliance before starting work to avoid shock
• Handle the board by its edges and avoid static discharge; use an anti-static strap if available
• Compare connectors and mounting points to the old board; transfer any brackets or harness clips if required
• Reconnect wiring securely and test basic functions after reassembly
