Safe Disconnect — Power, Water & Gas: the full procedure
De-energize and isolate the appliance from power, water, and (where present) gas before any hands-on repair, deferring gas isolation to a qualified technician.
- Applies to: All technicians, before any repair
- Frequency: Every repair, before component access
- Scope: Defines the mandatory disconnect sequence before opening an appliance. Always disconnect power first. Electrical lockout, gas isolation, and refrigerant systems defer to the manufacturer’s service information, a licensed/certified technician, EPA 608, OSHA, and the business safety plan.
What you need
- Multimeter (verify de-energized)
- Non-contact voltage tester
- Lockout/tagout supplies
- Water shutoff knowledge
- Towels/bucket
- Manufacturer service info
The procedure, step by step
- Disconnect electrical power first — Unplug the appliance or, for hardwired units, follow the business safety plan and manufacturer service info to de-energize at the breaker. Always disconnect power first.
- Verify zero energy — Confirm the appliance is de-energized using a tester/multimeter before touching internal components, per OSHA and the safety plan.
- Apply lockout/tagout if applicable — Where a breaker or disconnect is used, apply lockout/tagout per OSHA and the business safety plan so power cannot be restored unexpectedly.
- Shut off water supply — For washers and dishwashers, close the hot/cold supply valves and relieve pressure before disconnecting hoses.
- Defer gas isolation — For gas ranges and gas dryers, do NOT perform gas-line work. Stop and hand gas isolation and connection to a licensed/certified gas technician per manufacturer service info.
- Defer sealed refrigerant systems — Do NOT open or service any sealed refrigerant circuit. Refrigerant recovery and sealed-system work require an EPA Section 608-certified technician.
- Stage the work area — Protect floors, capture residual water, and keep disconnect status visible until work is complete and verified.
Quality check before you finish
- Electrical power disconnected first and verified de-energized
- Lockout/tagout applied where a disconnect/breaker is used
- Water supply valves closed and pressure relieved before hose removal
- Gas isolation deferred to a licensed/certified gas technician
- Sealed refrigerant work deferred to an EPA 608-certified technician
- Work area protected and disconnect status kept visible
This is a free, source-anchored standard operating procedure (SOP) you can print and hand to staff. It documents the work sequence for a Appliance Repair business — not safety or regulatory rulings, which defer to the cited authorities, the applicable code, and your own health-and-safety plan.

Frequently asked questions
What gets disconnected first on an appliance repair?
Power, always. Disconnect electrical power first and verify the appliance is de-energized before touching components, then isolate water for washers and dishwashers. Lockout/tagout follows OSHA's control-of-hazardous-energy rules and your business safety plan.
Can a technician disconnect the gas line or open the refrigerant system?
No. Gas-line isolation must be handled by a licensed/certified gas technician under the manufacturer's service information, and any sealed refrigerant work requires EPA Section 608 certification. These SOPs explicitly stop and defer at gas and refrigerant.
