# Lay-Z-Spa WiFi not connecting: what to check Source: https://bubbleandsoak.co.uk/blog/lay-z-spa-wifi-not-connecting Published: 2026-10-12 Publisher: Bubble and Soak **In short:** Most Lay-Z-Spa WiFi problems come down to the router band, weak signal at the tub or pairing steps. Check that your phone is on the 2.4 GHz network if the app asks for it, move the router or add an outdoor extender, put the pump unit in pairing mode as the manual shows, and re-add the tub in the app. If it still fails, power cycle the pump and contact Bestway. Smart Lay-Z-Spa tubs let you heat, set timers and turn on the bubbles from your phone. When the app cannot find the tub, or the tub keeps dropping offline, it is frustrating, especially if you were planning to warm it up on the way home. The cause is usually simple: the wrong WiFi band, a weak signal at the bottom of the garden or a pairing step missed. This guide works through the checks in order. Exact steps vary by model and app version, so keep your manual to hand. ## Quick checks first If the router details changed, the tub will not reconnect by itself. You will need to pair it again. - Is the pump unit switched on, with the display lit? - Is your home WiFi working elsewhere in the house? - Is the app up to date on your phone? - Is your phone's Bluetooth and location turned on, if the app asks for them during setup? - Has your router name or password changed since the tub was paired? ## Check the WiFi band Many smart home devices, including many hot tub pump units, connect only to 2.4 GHz WiFi, not 5 GHz. Modern routers often broadcast both under one name. If pairing fails, check the manual or the app's instructions; you may need to connect your phone to the 2.4 GHz network during setup, or enable a separate 2.4 GHz name in the router settings. 2.4 GHz also travels further through walls and across a garden than 5 GHz, which helps when the tub is some distance from the house. ## Check the signal at the tub The pump unit's WiFi module is small, and walls, glass with metal coatings and distance all weaken the signal. Stand by the tub with your phone on the home network and see how many bars you get. If the signal is weak, move the router closer, add a mesh point near a rear window, or use an outdoor rated extender. Keep extenders and their plugs away from water and use weatherproof sockets outdoors. Note: Hot tubs combine water and mains electricity. Use a weatherproof outdoor socket protected by an RCD, follow the maker's manual, and have any new circuit or socket fitted by a qualified electrician. ## Re-pair the tub step by step 1. Remove the tub from the app if it shows as offline. 2. Power cycle the pump unit: switch off at the socket, wait a minute, switch on. 3. Put the pump unit into pairing mode as your manual describes; often a button is held until a WiFi symbol flashes. 4. In the app, add a device and follow the prompts, choosing the 2.4 GHz network if asked. 5. Enter your WiFi password carefully; it is case sensitive. 6. Keep your phone near the pump unit until pairing completes. ## If it connects but keeps dropping Intermittent drops usually point to weak or busy WiFi. Routers sometimes change channel or restart overnight; give the tub a stable signal and check whether the drop happens at the same time each day. Some routers have settings that block smart devices; look for options such as band steering or client isolation and check the router's help pages. If the tub works but the app shows old data, log out and back in, or reinstall the app. Your heating schedule is usually stored on the pump unit, but check it after any reset. ## When to contact Bestway If the WiFi symbol never lights, the pump unit will not enter pairing mode, or the tub still will not connect after the checks above, contact Bestway's UK support with your model number and the app version. The tub itself still works from the control panel, so you can heat and run bubbles by hand meanwhile. Thinking of a different smart tub?

Check your manual; if pairing fails on a dual band router, try connecting your phone to 2.4 GHz during setup. **Why does my Lay-Z-Spa keep going offline?** Usually a weak signal at the tub or router changes. Boost the signal near the garden and re-pair if the router details changed. **Can I still use the tub without the app?** Yes. The control panel on the pump unit works without WiFi. **Does resetting the pump unit lose my settings?** It may reset some settings such as timers. Check them after a reset or re-pair. ## Buying guides on this topic - https://bubbleandsoak.co.uk/best/lay-z-spa-models-compared - https://bubbleandsoak.co.uk/best/best-premium-inflatable-hot-tubs - https://bubbleandsoak.co.uk/best/best-inflatable-hot-tubs
