- Check that the pitcher is not overfilled.
The water marking provides the measurement used to fill the appliance’s reservoir.
Step 2: Fill the Water Reservoir
- Rotate the brewing head to provide access to the water reservoir.
- Pour the measured water from the pitcher into the reservoir.
- Check the water level through the water window.
The reservoir must not be overfilled.
Step 3: Add Tea to the Brew Basket
- Open the top lid.
- Make sure the removable brew basket is correctly installed.
- Add the desired amount of tea.
- Use tea bags or loose tea with the permanent filter.
For a full 2.5-quart batch, the manufacturer recommends:
| Tea Type | Recommended Quantity |
| Tea Bags | 5–7 tea bags |
| Loose Tea | 2–3 tablespoons |
| Brewed Iced Tea | 2.5 quarts |
The quantity of tea may be adjusted according to the desired flavor.
Step 4: Add Optional Flavorings
Sugar, lemon, or other desired flavorings may be placed in the brew basket with the tea.
The flavorings are incorporated during the brewing process.
Step 5: Position the Rotating Shower Head
After the tea has been added:
- Rotate the shower head into its brewing position above the brew basket.
- Make sure it is correctly positioned.
- Close the top lid securely.
The lid must remain closed while the appliance is brewing.
Step 6: Adjust the Brew Strength
Use the adjustable steeping lever to select the desired tea strength.
The steeping control changes the amount of time the tea is allowed to steep during brewing.
A longer steeping period produces a stronger, fuller-flavored tea.
Step 7: Fill the Pitcher with Ice
Fill the pitcher with ice cubes to the designated ice-level marking.
The ice helps cool the brewed tea as it enters the pitcher.

Troubleshooting Guide
The following troubleshooting information covers operating conditions described in the Oster TM20 Series instructions.
| Problem or Symptom | Possible Cause or Condition | Recommended Action |
| Excessive steam during brewing | Mineral deposits may have accumulated in the brewing system. | Run the recommended vinegar descaling procedure. |
| Water stops pumping before the reservoir is empty | Mineral buildup may be affecting the brewing system. | Descale the appliance using 1 quart of undiluted white household vinegar. |
| Brewing begins when the appliance is plugged in | The ON button may have been pressed unintentionally. | Disconnect the plug if the cycle must be stopped. Complete the required preparation before reconnecting power. |
| Brewed tea becomes cloudy after cooling | Naturally occurring tannic acids in tea can cause cloudiness. | This is a normal condition described by the manufacturer. |
| Pitcher may overflow when cold water replaces ice | The pitcher has been filled to the ICE marking instead of the WATER marking. | When substituting cold water for ice, fill only to the WATER marking. |
| Brewed tea is not at the desired strength | The tea quantity or steeping setting may need adjustment. | Adjust the amount of tea or the brew strength control. |
| Pitcher is cracked or damaged | The pitcher has experienced damage. | Do not use the cracked pitcher. Contact Oster for replacement pitcher information. |
| Appliance has a damaged cord or plug or malfunctions | An electrical or mechanical fault may be present. | Stop using the appliance and contact an authorized service center. |
Iced Tea Maker Produces Too Much Steam
An increase in steam production can indicate mineral deposits inside the appliance.
The manufacturer recommends descaling the system using undiluted white household vinegar.
The cleaning frequency depends on whether the water supply is soft or hard.
Water Stops Pumping During Brewing
If the pumping process stops before all the water has moved through the appliance, mineral buildup may be affecting the brewing system.
The manufacturer identifies this as a condition that calls for descaling.
The recommended cleaning process uses 1 quart of white vinegar, a 30-minute soaking period, and a clean-water rinse cycle.
Iced Tea Maker Starts When Plugged In
The appliance may begin a brewing cycle when connected to electrical power if the ON button was previously pressed accidentally.
To stop the appliance during a brewing cycle, disconnect the molded plug from the electrical outlet.
Before restarting, the water reservoir must be filled, the top lid closed, and the pitcher correctly positioned.
Brewed Iced Tea Looks Cloudy
Iced tea may develop a cloudy appearance as it cools.
The manufacturer explains that this can occur because tea naturally contains tannic acids.
Pitcher Overflows During Brewing
When ice is unavailable, cold water may be placed in the pitcher instead.
However, the cold water must reach only the WATER-level marking.
Filling the pitcher with cold water to the ICE-level marking can cause overflow as the freshly brewed tea enters.
When to Contact Customer Service
The appliance must not be operated if its electrical cord or plug is damaged, it malfunctions, or it has suffered other damage.
Service covers must not be removed, and internal repairs must not be attempted.
All repairs must be performed by Sunbeam or an authorized Oster service center.
