Product Usage Instructions

Installation Requirements
- Before installing the dishwasher, ensure that the surrounding area is suitable and meets the following requirements:
- Condensate can build up, so ensure cabinetry and fittings are steam-resistant.
- Use the protective sheet provided to protect the countertop from steam damage.
Electrical Connection
- For electrical connection:
- All electrical work should be done by Miele Customer Service, an authorized dealer, or a qualified electrician.
- The dishwasher should be connected to an electrical outlet.
Water Connection
- When connecting the water supply:
- Vent the water supply pipe to avoid pressure surges that may damage components.
- Lay the drain hose properly to prevent kinks or pressure.
Built-under Appliances
- For built-under appliances (PFD 401 U):
- Follow the appliance dimensions for proper installation.
External Dispensing
- When using external dispensing systems:
- Connect up to two dispensing systems for cleaning agents at the back of the dishwasher.
- Ensure proper placement of containers and hoses as specified.

FAQs

Q: Can I connect the dishwasher to any power outlet?
- A: The dishwasher should be connected to the electricity supply via an electrical outlet. For specific voltage requirements, refer to the product manual.
Q: How should I lay the drain hose to avoid issues during operation?
- A: Ensure the drain hose is not kinked, does not undergo pressure, and is positioned to prevent siphoning effects. Follow the guidelines provided in the manual for proper drainage.

Installation notes

For safe installation and commissioning of the dishwasher, please read the installation plan, the service documentation, and the operating instructions. This installation plan includes the dimensions of the appliance, the technical data, and the requirements to be met on-site for the installation of the dishwasher.

Installation requirements
- Installation and commissioning work should be performed by a qualified and trained service technician following local and national safety regulations.
- Installation must comply with all local codes and regulations.
Surrounding area
- Condensate can build up in the area surrounding the dishwasher. Any cabinetry and fittings in the room must, therefore, be suitable for this purpose.
Protective sheet for built-under appliances
- The protective sheet supplied protects the countertop from damage caused by steam escaping when the door is opened. Fit the protective sheet above the door and underneath the countertop.
Electrical connection
- All work on the electrical connection should be carried out by Miele Customer Service, an authorized Miele dealer, or a qualified electrician.
Plug Connection
- The dishwasher should be connected to the electricity supply via an electrical outlet. PFD 401, PFD 404: 208 V Configuration Cord with plug is provided for use in commercial applications only – for installation observe your domestic electrical code.
Hard-wired
- If the dishwasher is hard-wired to the power supply, a circuit breaker capable of disconnecting the dishwasher at all poles must be installed on-site.
- This power switch must have a contact gap of at least 1/8″(3 mm). The electrical socket outlet and the circuit breaker must be accessible after the appliance has been installed.
- This is to enable an electrical safety test to be carried out after installation and after any servicing work.
- The power cord must be laid protected from the risk of thermal damage.
Equipotential bonding and grounding
- This machine must be grounded per local code.
Water connection
- Before connecting the dishwasher or immediately following a disruption in the water supply the water supply pipe must be vented from air pockets to avoid pressure surges that may destroy components in the dishwasher.
Water supply
- The quality of the incoming water must correspond to the drinking water specification of the country in which the dishwasher is being operated.
- The dishwasher must be connected to the water supply in strict accordance with current local and national water authority regulations.
- The dishwasher is connected to cold or hot water supplies. If hot water is not available, the two water inlet hoses (for cold and hot water) must be connected to the cold water supply via a Y-piece.
- The shut-off valves should remain accessible once the dishwasher has been installed so that the water supply can be shut off whenever the appliance is not in use.
Drainage
- The dishwasher drainage hose should be connected to a separate onsite drain for the dishwasher only.
- If no separate drain is available, we recommend connecting it to a dual-chamber siphon. When using a drain loop additional backflow prevention is not required.
- If the hose is to be directly connected to the drainage outlet on-site, use the hose clip supplied with the dishwasher.
- The on-site connector for the drain hose can be used for various hose diameters. If the connector extends more than 1″ (30 mm) into the drain hose, it must be shortened. Otherwise, the drain hose can become clogged.
- Lay the drain hose so that it does not kink and is not being subjected to pressure or tugged.
- If the on-site drain connection is situated lower than the guide path for the lower basket rollers in the open door, a siphoning effect during a program can cause the appliance to empty itself of water.
- In this case, lay the drain hose with a bend in it so that its highest point is at least level with the guide path for the lower basket rollers.
Connecting an external dispensing system
- Up to two dispensing systems for liquid cleaning agents and rinsing agents can be connected to the back of the dishwasher.
- Appliances with integrated dispensing systems have an external connection for rinsing agents.
