I measure a <2VAC drop when the heater is under load. Have an electrician check and confirm that the wire connections at the breaker or water heater are tight and firm. with dimmers can be very sensitive to voltage changes. I checked the connections all the way back to the main and the main service itself everything appeared to be ok. I checked the ground connection and it appears to be fine. Same issue here! Flickering can be caused by many other reasons, such as power surges, bad dimmers, loose connections, dust and debris in the fixture, etc. The water heater has 2 60 amp 240 v lines going to it. The fixture will just be a regular ole inclosed fixture containing CFL(s). @Peter Duniho - Correct, this is only when hot water is on. However, the circuit has the same limitations either way, and a voltage drop of just a few volts on the linear regulator puts it into drop out. Check both sets of breakers to make sure both sets of feed wires are 240V. I've contacted the power company an an electrician to come out next week, but any other ideas? As a reminder, the issue is not that the lights dim, it's that they rapidly flicker. Is it coincident with pump or freezer starting? Heres What to Do, Getting an Electric Shock when you Touch a Microwave? If those are mains leds, try them in a desktop lamp. If the elements would come on and stay on the lights would blink on startup, then be fine. It also runs an electric tankless water heater. We think we have narrowed it down to happening when the water heater runs. For comparison, if you replaced a tank type water heater they typically have 2 4,500 watt elements but only one is on at a time for a current draw of just under 20 amps. LEDs esp. Uff, all the LED bulbs I've opened are significantly more complex and actually regulate. Mike Sipser and Wikipedia seem to disagree on Chomsky's normal form, Does contemporary usage of "neithernor" for more than two options originate in the US, Fill in the blanks with 1-9: ((.-.)^. I'm assuming that at certain temp settings matches with certain flow rates would make the element relays kick in and out, causing the flicker. It depends on the type of tank you have. Weve taken many calls on this issue, and while we are happy to come out and help members confirm there is nothing wrong with their electric service. The breakers do not get hot. G A typical LED bulb is made of ~3v diodes arranged in series hooked up to a rectifier and a current limiting element (either a capacitor/resistor as in this diagram or more commonly in the USA a linear regulator on the DC side): In this design the LEDs are stacked up to be close to the rectified mains voltage so that losses are low in the resistor/regulator. To learn more, see our tips on writing great answers. Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. They flicker like a GM taillight since each string is on only at the peak of its half cycle. AFAIK those heaters are pretty simple and cycle elements on/off to maintain temp instead of using a faster PWM - no way around the source of the problem - maybe a tank heater? If there's a lot of dust in the fixture, first blow out the connection points to remove the dust before putting the bulb back in. Confirm with the power company that the service cable to your house and the current (amps) are appropriately sized and sufficient to meet the power requirements of the water heater.

That said, all our LEDS are good down to 90V, so if it's really that bad you may well have noticed other issues. Use MathJax to format equations. I figure with the main living area ceiling lights on (7 LED lights) when the pump runs the single 15amp feed to that panel is insufficient (or maybe the wiring is undersized). Have an electrician confirm this. Thread: Water pump runs = flickering overhead LED lights. I wired a garage for a guy and he (against my recommendation) got a tankless water heater. People who buy mail-order or who buy cheap are particularly vulnerable to encountering this crud. Face it, a tank water heater runs off 30 amps and provides ample hot water. -Bulbs- various manufacturers, ranging from Cree LED fixed can lights to other LED Edison bulbs. Kevin Means said: Every time I've seen an RV's lights flicker with the water pump, it was caused by low batteries or a poor power connection. With plenty of options to fit your needs and prices coming down, we recommend making the switch. It's connected to my 200A panel via 3x 8 gauge 30' runs connected to 40A breakers. Elements seem to be working ok We already had an electrician come and they spent 2 hours checking outlets, etc, and not finding anything of significance. to this site, and use it for non-commercial use subject to our terms of use. I have some in my home, on the same dimmer that dim at slightly different rates even though they are on the same circuit/dimmer. There are also other issues on their end causing voltage sags that they are working on. New Murray breakers (2 x double pole 40 AMP). You say you ran 8 gauge Romex, I assume that's 2 runs one for each 240volt breaker. How do two equations multiply left by left equals right by right? After running the washer for a few min there was a drastic drop in all of the LED's in the house as well as some flickering.

B BillyMac59 If either leg drops below 105 Vac, you have some issues. @Nstorm As I said the most common configuration in the USA is a linear regulator placed on the DC side rather than a capacitive dropper. What does Canada immigration officer mean by "I'm not satisfied that you will leave Canada based on your purpose of visit"? That is a power outage at the pole, which the power company will fix for free, but it's devilishly difficult to detect. It only takes a minute to sign up. If I center the present fixture it will be right next to the smoke detector (within a few inches). Standard LEDs cannot be dimmed this way, so the switch causes them to flicker. All rights reserved. Have you measured the voltage at the led lights. the poco xfmr is probably 25kva for multiple house so, it is probably overloaded too much. (unless those little ones under the kitchen sink) Gas ones are fantastic. Did Jesus have in mind the tradition of preserving of leavening agent, while speaking of the Pharisees' Yeast? Adjusting the temperature a degree or two would take care of it. How do you stop LED lights from flashing fast? Is it one particular type of LED or do all LED types flicker? LED circuits can be designed to reduce flicker by adding capacitance and using a full bridge rectifier or inverter to convert AC to DC, but cheap Christmas light strings may not use a full bridge rectifier, which would cause flicker at around 50/60 Hz. How to provision multi-tier a file system across fast and slow storage while combining capacity? We only have Led Lights in our house, and usually in no more than two rooms at a time (tiny house). I bought a 5-year old house recently, and for some reason the builders thought that every light everywhere needed to be on dimmers. The transformer may be too small. Hopefully your heating system isn't also electric. Because leds do not act the same way for dimming, Led rated dimmers and dimmer rated led bulbs. Has anyone ran into this before?
