Want to know water and energy ratings of WFL2000AU.

Likely too old for an Energy Star Rating.

What is the efficiency of a gas wall furnace?
Wall Furnace Energy Efficiency Ratings

Today's wall furnaces are often rated at 80 to 90 percent annual fuel utilization efficiency (AFUE).Jan 26, 2021

Everything You Need to Know About a Wall Furnace - Family Handyman

If you pick a brand, the site will have the ratings. There are also some resources on energy websites. The best rated water heaters for energy ratings are very expensive because they are the tankless models. If you don't want to spend thousands on a water heater, I would recommend RHEEM brand heaters. If you are replacing an older unit you need to know that the newer models are bigger and may not fit directly in the place of the old one.

It is under the unit.

Rheem 50 gallon Pro52-2 has EF .95, which makes it ordinary 240Volt 4500 watt non-simultaneous electric water heater that produces about 21 gallons hot water per hour, with 67 gallon first hour delivery.
Recommend 80 gallon per hour first hour for oversized bathtub.

Maintain electric water heater and it will last indefinitely.

Anode rod is located on top in separate port.
Anode keeps tank from rusting.

Year of Rheem water heater manufacture shows 3rd and 4th digit of serial number.

You want to know if this heater has Energy Star label.
I don't know.
Call Whirlpool 1-877-817-6750

Energy Star is a label that means nothing to you.
Manufacturers use energy-star label to promote a product as a money-saver.
They can put an Energy Star label on a giant 10,000 square foot house, and you know that cannot be the truth that a large house saves energy vrs a smaller house.

Energy factor, (energy factor/ not energy star) on the other hand, is a comparison measure how efficient the water heater uses energy to heat a gallon of water, when water heater is absolutely new.
EE3J50RD045V has energy factor of .59, which is completely typical and ordinary for electric water heaters.

The EE3j 50 gallon is an ordinary electric water heater, with ordinary average .59 energy factor rating, so electricity to operate this water heater is same as any other typical 50 gallon electric water heater: it will cost $35-45 a month depending on incoming water temperature, hot water use, thermostatic setting, electricity pricing, and whether you operate heater at peak pricing, etc.

The most important measure of water heater cost does not have anything to do with Energy-star or energy-factor.
The most important measure is total cost of owning and operating the water heater.
So if you spend $100 more to purchase electric water heater with slightly higher energy factor, then it will not pay you back. The difference will be $2 to $4 per year.
All costs are energy.
The total cost of operating water heater includes purchase price, installation cost, cost of repairs, cost of parts, whether you can fix it yourself, expected life of water heater, and replacement cost.
Every water heater has expected lifespan, and will not have resale value except current price of scrap.

Electric water heaters cost more to operate per month than same-size gas water heater.
Gas water heater might cost less over the life of water heater, but gas water heaters are increasingly expensive to repair, and increasingly more complicated, and cost more up-front to buy.

Electric water heaters cost less to buy, are easy to install yourself, are fully repairable by homeowner using generic off-the-shelf parts, and can be made to last many years by keeping tank clean and replacing anode rod every 2 years.
You can make ordinary 6-year electric water heater from box store last almost indefinitely.
Avoid electric water water heater that has electronic controls.

Reliance is AO Smith company.

1) Reliance does not post the 501 manual any more and I've written and asked for that manual, and they sent generic manual. Model 501 is both gas and electric.

2) That tells me the old energy factor is probably lower than .54 approximately, but it will be even less because energy factors are for new water heaters in perfect operating order under ideal conditions.

3) Energy factor is a measure of how efficiently the water heater turns energy BTUs into hot water.
Gas water heaters have higher energy factor because gas burner has more BTU punch than electric element, and can heat water faster.

4) However, energy factor is not measure of actual cost. It is merely a way to compare giant water heaters with smaller heaters, and gas with electric, without considering cost of heater, installation cost, repair costs, parts costs, life expectation of unit, disposal/recycling cost, or replacement cost.

5) You can improve your true energy factor by buying small cheap heater and maintaining it yourself so it lasts many years beyond manufacturer's warranty.

6) If someone buys a bigger water heater because it has better energy factor, it will not pay back the higher purchase cost. Same size to same size, the difference with higher energy factor is a few dollars per year.

7) If you have sediment inside of tank, the energy factor is out the window.

55 gallon has .90 energy factor.

4500 watt water heater costs about $48 per month with electric prices at 12 cents per Kwh

Read about energy factor:
http://www.energysavers.gov/your_home/water_heating/index.cfm/mytopic=13000
"...energy efficiency based on the amount of hot water produced per unit of fuel consumed over a typical day. This includes the following:

• Recovery efficiency - how efficiently the heat from the energy source is transferred to the water
• Standby losses - the percentage of heat loss per hour from the stored water compared to the heat content of the water (water heaters with storage tanks)
• Cycling losses - the loss of heat as the water circulates through a water heater tank, and/or inlet and outlet pipes." end quote

Energy factors exist so large appliances can be compared to small appliances.
-This is like comparing aircraft-carriers to small ships.
-The purpose is so large gigantic appliances look like reasonable energy alternatives, when that is not actually true.
-The aircraft carrier could have better efficiency number than smaller ship, and it gives misleading appearance that aircraft-carrier will save the consumer money. Many of the super high-consumption 80 gallon water heaters have higher energy factor, but they consume huge amounts of energy each time operated. Simple Dort series is a better value even with lower efficiency number.
-The efficiency number is only for a new product. There is no measure showing how long that product will maintain the efficiency rating.
-And lastly, the manufacturer is putting energy factor on the product, like writing your own performance review, so who can possibly double-check the energy factor.

If there is no water in washer, and it will not spin, I suggest you remove the motor, and check the brushes.
If they are less than 3 or 4mm long, they need replacing.
Hope this helps.

Here is energy guide for your washer machine

ALL ENERGY STAR APPLIANCES HAVE A "ENERGY-STAR LABEL" USUALLY LOCATED ON OR NEAR THE MODEL AND SER. NUMBER TAG OR LABEL. CHECK ON THE BACK OR INSIDE THE REFRIGERATOR WHERE THE COLD CONTROLS ARE LOCATED.
