Control Panel Diagnosis
When a Pentair or Hayward panel throws an error code or goes dark, we read the board and the power supply to find the real failure point instead of quoting a full replacement on a guess.

Hillside Pool & Spa repairs pool automation across Round Rock, bringing dead panels, dropped app connections, and stuck schedules back online so your pool runs itself again.
A focused pool automation repair visit covers the specific problems that show up on Round Rock pools. Here is what we handle on every repair.
When a Pentair or Hayward panel throws an error code or goes dark, we read the board and the power supply to find the real failure point instead of quoting a full replacement on a guess.
App control that keeps dropping is usually a network module or a firmware mismatch, not a dead system. We re-pair the connection and update the firmware so your phone controls the pool again.
If your pump runs at midnight or the cleaner never starts, a relay on the board has likely failed. We swap the relay and reprogram the schedule so the pool runs the hours you actually set.
Wrong temperature readings or ignored freeze protection usually trace to a bad sensor probe or a corroded input terminal. We replace the probe and clean the contacts so the automation reacts to real conditions.
Valves that will not switch between spa and pool mode often have a burned-out actuator or a lost control signal. We repair the actuator path so the flow routes where the automation tells it to.
We cycle the full system, log every error, and hand you a written diagnosis before any part goes in. That paper trail is what keeps a repair from turning into a guessing game.
Most smart pools in Teravista and Forest Creek run Pentair IntelliTouch or EasyTouch, while the builds around Paloma Lake lean toward Hayward OmniLogic. Our techs know the firmware quirks and the common board failures on both platforms, so a panel that has stumped another tech often gets diagnosed on our first visit. Carrying the right diagnostic cable for each system is what speeds up the call.
We install genuine Pentair and Hayward relay modules, sensor probes, and network cards, because the aftermarket boards we have pulled out of failed systems tell us they do not last. Every component gets matched to your firmware version before it goes in, and we run a full cycle test before we pack up. A part that is not tested is a part that is not finished. For the full scope of our pool automation repair work across the area, see our Pool Automation Repair overview page.
We diagnose the real cause, send a clear written quote, and verify the fix before we leave your Round Rock backyard.
We run the automation through every mode, pull the error log, and test the board, the relays, the sensors, and the Wi-Fi link to trace the fault to its source.
Before any part is ordered, we write up the repair in plain language and send it over so you can approve the scope with no pressure.
We install the matched part, run the system through a full cycle, and confirm every schedule, valve, and sensor reads right before we leave your yard.
A broken automation system turns a hands-off pool into a daily chore, and the longer it runs faulty the more it drifts the chemistry and stresses the equipment. These warning signs mean a repair visit is the quickest way back to a pool that runs itself.
A relay that is arcing today can take the whole board out by next week, so catching the fault early is what keeps the repair small.
We test the board before we quote anything, because the line between a fix and a full swap depends on which part quit and how long the panel has been on the wall. One dead relay or a single bad sensor is a clean repair, but a control board that has burned through several traces usually points to a replacement. We put both roads in front of you with honest numbers and let you pick what fits your yard and your wallet. Nobody on our crew gets a bonus for selling the bigger job.
When a replacement is the smarter call, we send a free written quote after seeing the pad, and we size the new system to your equipment and your plumbing so nothing gets over- or under-built. You sign off on the scope before any work starts, so the bill never catches you off guard. The aim is an automation setup that runs for years, not one that gets us out the door fastest.

That familiarity is what shortens the diagnosis. See our full Round Rock pool service page for everything we offer in the area.
Automation calls in Round Rock track closely to the storm-season power blinks and the dense app-controlled setups across the newer master-planned sections. Here is what we plan around.
The open grid around Teravista and Paloma Lake takes storm-season power blinks that the digital panels do not absorb well, and a board that resets on its own after a blink often took a surge through the pad. We test the control board and the surge protection together, because replacing the board without fixing the surge path just sets up the next failure. Adding a dedicated surge protector on the pad is a step we recommend on almost every Round Rock automation call. The power pattern here is the first thing we ask about.
Round Rock's newer subdivisions pack a lot of smart homes onto a small grid, and the 2.4GHz congestion is a real cause of automation systems dropping off the app. The fix is often a failing network module or a router that got swapped without re-pairing the pool system, not a board failure. We repair the module, re-pair the connection, and move the system to a cleaner channel when the congestion is the real culprit. Knowing how crowded the wireless band is here shapes how we diagnose the dropout.
