Westinghouse pressure washers have become popular with homeowners for their combination of performance and value. But like any machine, parts wear out and eventually need replacement – nozzles, hoses, guns, pumps, and seals. Finding the right Westinghouse pressure washer parts is essential to keeping your machine running. This guide explains what parts commonly need replacing, where to find them, and how to identify the correct part for your model.
Westinghouse pressure washers are typically aimed at the residential and light-duty market, with both gas and electric models. Parts availability is generally good because parts are sold through online retailers, Westinghouse’s support channels, and aftermarket suppliers. The key is identifying your exact model number before ordering.
Common Parts That Need Replacing
| Part | Typical Replacement Reason |
|---|---|
| Nozzles | Wear, clogging, loss, damage |
| High-pressure hose | Kinks, cracks, leaks, burst |
| Spray gun / wand | Leaks, broken trigger, worn fittings |
| O-rings and seals | Leaks at connections |
| Pump | Wear, freeze damage, dry running |
| Inlet filter | Clogging, damage |
| Unloader valve | Pressure loss, bypass failure |
| Engine parts (gas) | Air filter, spark plug, fuel lines |
| Wheels and frame parts | Wear, breakage |
Nozzles, hoses, and O-rings are the most common replacements and are inexpensive. Pumps are the most expensive and usually replaced only when rebuild is not possible.

Identifying the Correct Part
- Find the model number. Look on the machine frame or in the manual.
- Note the serial number if available – some parts vary by production run.

- Use the parts diagram. Westinghouse parts diagrams show exploded views with part numbers.
- Confirm compatibility before ordering.
- Keep the receipt in case of returns.
Common Repair Scenarios
| Problem | Likely Part Needed |
|---|---|
| Leaking at hose connection | O-ring or fitting |
| Low pressure | Nozzle, unloader, valve, or worn pump |
| No water flow | Clogged inlet filter or nozzle |
| Hose burst | Replace high-pressure hose |
| Trigger won’t work | Spray gun replacement |
| Pump leaking/knocking | Seal kit or pump replacement |
Maintenance to Reduce Parts Replacement
- Winterize properly. Prevents freeze damage to the pump – the most common need for expensive parts.
- Never run dry. Protects the pump from damage.
- Clean the inlet filter. Prevents contamination and clogging.
- Rinse after chemicals. Prevents injector and seal damage.
- Store properly. Coil hoses and store dry and frost-free.
- Inspect O-rings. Replace worn ones before they leak.
