EL 05 Capacitor-50 uF Master/Evolution/V6 P80/P90
Capacitor for:
- Master P80
- Evolution P80 and P90
- V6 P90
This is a start capacitor rated at 50 µF, designed for AVA’s largest single-phase induction motors. It provides the initial boost of torque required to start the motor safely and reliably.
• A faulty or degraded capacitor can cause the motor to hum, fail to start, or trip the fuse on power-up.
• This component is used in the AVA Master and Evolution P80 and P90, as well as V6 P70 models with high-performance motors.
Note: This is a standard motor capacitor used across many heavy-duty machines. If choosing a third-party version, always ensure the capacitor is rated 50 µF, with matching voltage (typically 400–450V AC), and meets motor-grade safety and tolerance standards.
Can be replaced by most users, This capacitor is a simple, non-polarised component and can be replaced by anyone with basic tools and who takes safety precautions.
Typical cause of failure
• Electrical wear and ageing over time
• Overheating from frequent heavy-duty use
• Power surges or short circuits
• Mechanical damage or water intrusion in the motor housing
Failure symptoms – Part correlation
• Motor does not start or only hums
• Unit trips the fuse or circuit breaker on start-up
• Machine starts only with external assistance (e.g. spinning the fan)
• Visible deformation, bulging or leaking on the capacitor body
Capacitor failure is a common issue in motor-driven products. However, AVA has significantly reduced this risk by integrating a thermal switch into the motor, making capacitor-related problems very rare.
If you suspect a capacitor fault on your AVA machine, we recommend testing it before purchasing a replacement.
Note: A machine that hums or fails to start may also be caused by low voltage, excessive inlet water pressure, or a mechanical issue in the pump – not necessarily the capacitor.
Installation advice
Always unplug the machine and allow the capacitor to discharge before handling.
Always prioritize safety first: Safety instructions – AVA of Norway
Remove the housing to access the motor compartment
• Carefully disconnect the old capacitor, noting terminal orientation
• Replace with a 50 µF motor-rated start capacitor of the same shape and dimensions
• Ensure all terminals are secure and the capacitor is properly fixed to avoid vibration damage
Tools Needed for all AVA Pressure Washer Maintenance – AVA of Norway
Recommended service guides:
- Replace capacitor Master
- Replace capacitor Evolution
- V6 P70 follows similar procedures; contact support if clarification is needed
Troubleshooting a Start Capacitor
A faulty capacitor is a common reason why a pressure washer motor fails to start, hums without turning, or trips the fuse. If you suspect capacitor failure, it should be tested before replacement.
Method 1: Multimeter with Capacitance Mode (most accurate)
- Disconnect power and discharge the capacitor by shorting the terminals through a resistor (not directly with a screwdriver).
- Remove at least one terminal from the machine to isolate the capacitor.
- Set your multimeter to capacitance mode (symbol: “–|(–”).
- Connect probes to each terminal.
- Read the displayed value. It should match the printed rating (e.g. 35 µF ±5%).
If the reading is much lower or shows OL (open loop), the capacitor is faulty.
Method 2: Resistance Test (for basic multimeters)
- Set the multimeter to resistance (ohm) mode.
- Touch probes to the terminals. A good capacitor will:
- Show low resistance briefly, then rise (charging effect)
- Eventually display OL (open line) as it charges
- A bad capacitor will:
- Show zero (short) or constant low resistance
- Or show infinite resistance (open) with no charging reaction
Tip: Visual signs of failure (bulging, cracking, or leakage) are strong indicators that the capacitor needs replacing – even before testing.
Warranty and Self-Repair – The AVA Way
At AVA, we encourage repair – not throwaway culture. You’re free to open your machine, inspect it, and replace parts yourself without losing your warranty. That’s part of what makes owning an AVA product different.
We offer guides, spare parts and support so that you can keep your machine running for many years to come – whether it’s a simple nozzle, a carbon brush, or a full pump module.
Many parts are designed to be replaceable – just like they should be.
Visible signs of use or repair are welcomed – they mean the product is being cared for.
