The Dometic Model 147 is a popular choice for sanitation toilets, known for its reliability and ease of use. However, like any appliance, it may require occasional repairs or part replacements. Understanding the parts involved and how to troubleshoot common issues can save you time, money, and frustration. This guide provides a detailed parts list, addresses common problems, and helps you maintain your Dometic 147 toilet.
Understanding the Dometic 147 Toilet System
Before diving into the parts list, it's essential to grasp the basic components of the Dometic 147. This toilet utilizes a macerator system, which chops up waste before pumping it to a holding tank. This system consists of several key parts working together:
- Toilet Bowl: The porcelain bowl where waste is deposited.
- Macerator: The motor that grinds waste into smaller particles for easier pumping.
- Pump: The pump that forces the macerated waste into the holding tank.
- Holding Tank: A tank where waste is stored until disposal.
- Control Panel: The switch that activates the maceration and pumping process.
- Wiring and Connectors: The electrical connections that power the system.
- Seals and Gaskets: Various seals and gaskets ensure watertight operation and prevent leaks.
Dometic 147 Toilet Parts List: A Breakdown
While a complete exploded parts diagram is best obtained from the Dometic website or a authorized dealer, we can break down the essential components you might need to replace:
- Toilet Bowl: This is usually the last part to fail. Replacement is typically only required after significant damage.
- Macerator Impeller: This is a common wear item. The impeller is the rotating part that grinds the waste. Over time, it can wear down, causing poor maceration or complete failure.
- Pump Motor: The heart of the system. Failure can mean the pump no longer functions. This is typically diagnosed by lack of pumping action even with a functioning macerator.
- Pump Seals: These seals prevent leaks between the pump and other components. Deterioration or damage can lead to leaks.
- Holding Tank: If your holding tank cracks or develops leaks, replacement is necessary. Regular cleaning and maintenance help extend its life.
- Control Panel Switch: This is the switch used to activate the toilet's function. Replacement may be necessary if the switch malfunctions or breaks.
- Wiring Harness & Connectors: In cases of electrical failure, this could be the cause. Always check wiring for damage or disconnection before assuming a motor fault.
- Various Seals and Gaskets: A variety of seals and gaskets are used throughout the system. Regular inspection and replacement (as needed) prevent leaks.
