What causes high voltage in pool equipment?
High voltage is typically caused by utility company voltage regulation issues, loose electrical connections, or transformer problems. It can also result from using incorrect wire sizing or poor electrical installation practices.
Can high voltage damage my Hayward pool equipment?
Yes, voltage above 260V can damage control boards, motors, and other electronic components in Hayward pool equipment. The high voltage error is a protective feature to prevent this damage.
Is it safe to reset the high voltage error?
Only reset the error after confirming supply voltage is within the normal 220-240V range. Resetting without fixing the underlying voltage problem can cause permanent equipment damage.
How often should I check my pool equipment voltage?
Check voltage monthly during pool season or whenever you notice equipment malfunctions. Install a voltage monitor for continuous protection if high voltage is a recurring problem in your area.
Will my homeowner's insurance cover high voltage damage?
Coverage varies by policy, but many insurers cover electrical damage from utility company voltage issues. Document the high voltage readings and contact your insurance company to discuss coverage options.
