Lavamatic WS-10521 – 1 Piece

The Lavamatic WS-10521 electronic surge protector is designed to safeguard front- and top-load washing machines from voltage spikes, brownouts, and outages. It offers high-voltage shutoff at 140 VAC and low-voltage shutoff at 90 VAC, reducing risk of motor and control board damage. A delay period indicator lights up when plugged in or after a power outage, helping users monitor protection status. This unit focuses on washing machines and provides dedicated protection against common power irregularities that can affect laundry equipment.
Lavamatic WS-10521 – 2 Pieces

This 2-pack of Lavamatic surge protectors gives dual appliance coverage, ideal for households with separate washers or a dedicated laundry area. It preserves the same voltage protection range (90–140 VAC) and the same delay indicator feature as the single unit. Using two units reduces the risk of a single point of failure while maintaining consistent protection across machines and related laundry devices.
Two Electronic Voltage & Surge Protector Combo

The combo includes one Refrigmatic surge protector for a refrigerator and one Lavamatic protector for a washing machine. This setup is ideal when safeguarding two essential home appliances with different energy requirements. It provides protection against high and low voltage, brownouts, spikes, instant surges, outages, voltage fluctuations, and load shedding, helping extend the life of both major appliances.
Ortis Double Outlet Voltage Protector

The Ortis protector provides two outlets with clear status indicator lights for normal, high voltage, low voltage, and delay. It automatically cuts power when voltage exceeds safe ranges, helping prevent damage to a washer, dryer, or other household electronics. The dual-outlet design supports protecting two devices simultaneously, contributing to streamlined kitchen and laundry setups.
Supco APP120 Surge Protector

The Supco APP120 is designed for large appliances like refrigerators, washing machines, dryers, and air conditioners. It includes three indicators—Protection, Delay, and Ground—providing at-a-glance status. This protector focuses on critical appliances and aims to minimize damage from sudden blackouts or voltage irregularities, contributing to longer appliance life and fewer maintenance events.
Buying Guide: Key Purchase Considerations
When choosing a surge protector for washing machines and dryers, consider these aspects:
- Voltage protection range: Look for units with clear high- and low-voltage shutoff thresholds (commonly around 90–140 VAC). A wider range helps accommodate regional power variability.
- Delay and alarm features: Delay indicators let you verify protection status after power restoration, while audible or visual alarms alert you to outages or faults.
- Number of outlets: Decide between single-outlet or dual-outlet variants. For multi-appliance setups, dual-outlet protectors prevent overloading a single strip.
- Dedicated vs. multi-appliance protection: Some units are built for specific appliances; others protect multiple devices. Choose based on your laundry room and home layout.
- Mounting and form factor: Wall-mountable or plug-in designs save space and reduce clutter behind machines.
- Indicator clarity: Bright LED indicators help you quickly assess status and safety, especially in dim laundry rooms.
- Build quality: Look for surge protectors with durable housings and flame-retardant materials to guard against heat and wear.
- Compatibility with appliances: Check manufacturer recommendations and ensure the protector’s wattage and current ratings meet or exceed your washer and dryer requirements.
Performance Considerations And Use Cases
For households with frequent power fluctuations, a robust surge protector reduces repair costs and downtime. If your area experiences regular outages, a unit with a strong delay feature can prevent immediate restarts that cause mechanical stress. For homes with a fridge alongside a washer and dryer, a combo or dual-outlet solution can provide efficient, centralized protection. Finally, for spaces with limited outlets, multi-device protectors enable safer operation without needing extra power strips or adapters.
