Why Is Your ecobee Thermostat Frequently Rebooting? Honeywell T9 vs ecobee and More

What you're about to read

I'm a field service specialist with a regional HVAC and appliance company. Six years, about 200+ emergency calls, mostly residential. My experience is based on single-family homes and small apartments; if you're managing a commercial building, some of this won't apply the same way.

This is the list of questions I type out more than any other. It includes the exact phrase 'ecobee thermostat frequently rebooting' and the far less exciting 'how to disconnect a dishwasher.' Both are valid emergency calls in my world.

• Honeywell T9 vs ecobee: which one makes more sense

Let's get into it.

1. Why is my ecobee thermostat frequently rebooting?

If you searched that exact phrase, you're not alone. I've had ecobee rebooting calls in the middle of winter, and they're almost never about the thermostat being dead. Between October and December 2024, I tracked 40 reboot-related calls. About 8 out of 10 were power-related.

ecobee thermostats need a common wire, usually called a C wire, to keep the screen powered all the time. When there's no C wire, the thermostat borrows power from the heating and cooling system. That works fine until the system turns on and the voltage fluctuates. Then you get the ecobee logo, black screen, reboot, repeat.

The first thing I check is whether a Power Extender Kit was included and installed. Per ecobee's installation guide, the Power Extender Kit is designed for homes with no C wire, and it solves a lot of power issues without running new wire. The second thing I check is the furnace door safety switch. If the furnace door isn't seated properly, the system can lose power and the thermostat will act like it's rebooting.

Last December I had a homeowner ready to buy a new thermostat because the ecobee kept cycling. It was -12°F outside, and I had to decide between talking them through a full wiring check or starting with the basics. In hindsight, I should have asked about the air filter first. That was the whole problem. A clogged filter made the blower work harder, caused a voltage dip, and the thermostat kept rebooting. So before you pull the thermostat off the wall, check the filter.

If reboots happen only when the compressor kicks in, you might have a wiring or transformer issue. That's a different animal and worth a service call.

2. Honeywell T9 vs ecobee: which one should I pick?

I don't like telling people one brand is clearly better, because both are solid. But I'll give you my honest take as of January 2025: if you want a thermostat that installs with less back-and-forth and has broader smart home integration, choose ecobee. If you want a straightforward thermostat with easy room sensors and you don't care about Alexa or HomeKit, the Honeywell T9 is a strong pick.

Here's the difference in plain language:

• Honeywell T9: simple interface, solid remote room sensors, and the app is easy to understand. It's a good thermostat if you just want comfort control.
• ecobee: built-in Alexa, Apple HomeKit support, and better integration with HVAC equipment. If you're installing for a Carrier or Rheem system, ecobee is often the more direct fit.

For contractors, efficiency is a bigger deal than brand loyalty. ecobee's install app asks the right questions before you connect the wires, which means fewer callbacks. I've done enough installs to know that a thermostat that asks 'do you have a C wire?' before you finish is worth the time on a busy day.

I do not think you're making a mistake with either one. But if you ask me personally, the ecobee is the better long-term investment for a homeowner who wants energy data and smart home features. The T9 is the one I'd suggest if someone just wants to set a temperature and never think about it again.

3. Where can I find a Farberware countertop dishwasher manual PDF?

This question is more common than you'd think. The official Farberware support site is the best place, not a random PDF link from a search result. Look for the model number on the sticker on the side or back of the dishwasher, then go to the support section and download the manual for that exact model.

Countertop dishwasher manuals can look the same, but they aren't. The drain hose setup and water inlet requirements are different between a 6-place setting unit and an 8-place setting unit. A generic PDF might tell you the wrong max distance for the drain line.

One thing I tell customers: don't skip the manual just because the unit looks easy. I've unboxed enough countertop dishwashers to know the biggest failure is installing the drain hose at the wrong height. That causes backflow, and a dishwasher that won't drain is not an appliance, it's a headache.

Take this with a grain of salt. I'm not a Farberware factory technician. I'm an appliance tech who has seen the results when people trust a manual that doesn't match their model.

Stick to the manufacturer's official PDF. It's the same manual the repair tech would check, and it prevents most installation problems.

4. How do I pair a Samsung remote with Smart Hub?

If your Samsung remote stopped working after a Smart Hub update or a network change, try the simple reset first. Turn off the TV, unplug it for 30 seconds, and then turn it back on. Press the remote's power button. I keep notes on this because it works on more than half the Samsung TVs I've run into.

If that doesn't work, the remote needs to be paired again. Newer Samsung remotes connect using Bluetooth. The method I use is this: hold the Play/Pause and Back buttons at the same time for about 5 seconds, wait for the pairing message, and test the remote.

If it still doesn't pair, hold the Power button and Volume Up together for 10 seconds to reset the remote. I'm not 100% sure that works on every model, but it's worth trying before you order a replacement.

The Smart Hub part comes in when you're using the remote to control SmartThings devices. Make sure the TV and the phone with the SmartThings app are on the same Wi-Fi network. I had a call where the remote was working, but the TV had joined the guest network and lost connection to the smart hubs in the house. That was a network issue, not a remote issue.

5. Why do my ecobee and Samsung TV reboot when I run the dishwasher?

This is the question nobody asks until it happens, and I honestly didn't expect it either. When a dishwasher motor starts, it can draw a big spike of current. In an older home, that can cause a brief voltage drop. A sensitive thermostat or TV can see that drop and reboot, even though the dishwasher itself is fine.

The same thing can happen with a space heater or refrigerator. If your ecobee has a marginal C wire connection, it's even more likely to reboot during those voltage dips. I once spent two hours troubleshooting a thermostat that rebooted every time the fridge compressor kicked on. The fix wasn't the thermostat. It was a shared circuit that couldn't handle the load.

What I'd do: check which circuits feed the dishwasher, the TV, and the thermostat. Ideally the dishwasher has a dedicated circuit. If it's sharing with sensitive electronics, move the TV or thermostat to another circuit, or call an electrician to split the circuit. That is not a DIY job unless you're comfortable with a breaker panel.

Separating the loads is the real fix. The thermostat might stop rebooting for other reasons after that, but this is the hidden cause people forget.

6. How to disconnect a dishwasher safely

This one can turn into a real emergency if it's done in the wrong order. A dishwasher has power, water, and drain. The most important rule is shut off power first, then water, then drain.

1. Shut off the power at the breaker. If it's a plug-in model, unplug it. If it's hardwired, test with a voltage tester after shutting off the breaker.
2. Turn off the water supply. There is usually a shut-off valve under the sink. If there isn't one, turn off the main water valve.
3. Disconnect the drain hose with a bucket ready. There is always water left in that hose.
4. Disconnect the water supply line, then cap or plug it.
5. If the dishwasher is hardwired, secure the wires with wire connectors so they can't touch anything metal.

I had a call in 2023 where someone tried to move a dishwasher without disconnecting the water supply first. They didn't flood the kitchen, but they did crack a shut-off valve that was already corroded. That's a $300 mistake that could have been free if they had taken five extra minutes.

For a countertop dishwasher, the process is easier because it's usually plug-in and uses a faucet adapter. But you still need to let the drain hose empty into a shallow pan, not a bucket. A bucket can splash, and a shallow pan lets you see when the water stops.

If you're not confident, call a professional. A flooded kitchen is a lot more expensive than a service visit.
