How to Drain a Baby Brezza Bottle Washer Pro

To drain a Baby Brezza Bottle Washer Pro, remove the waste water tank from the base, empty it into a sink, rinse and dry the tank, then slide it back into place. If you are putting the machine away or moving it, empty the clean water tank as well. The Bottle Washer Pro does not need a plumbing drain hose or a drain plug for normal emptying.

What Draining the Bottle Washer Pro Means

The Bottle Washer Pro uses two separate removable tanks:

The clean water tank holds fresh water for washing, sterilizing, and drying cycles.
The waste water tank collects the dirty water after a cycle.

For normal use, “draining” means emptying the waste water tank. You only need to empty the clean water tank when you are changing the water, preparing the machine for storage, or carrying it somewhere.

Use the labels on your machine to identify the tanks. The Bottle Washer Pro manual in Baby Brezza’s official user-manual library can help identify version-specific parts.

Do not look for a plumbing-style drain plug underneath the machine.

Use this table to match each situation with the tank to empty and the next step:

Situation	Tank to Empty	What to Do Next
A wash cycle has finished	Waste water tank	Empty, rinse, dry, and reinstall it
You are not using the washer again soon	Waste water tank	Empty, rinse, dry, and reinstall it
You are storing or transporting the machine	Both tanks	Empty both, rinse and dry the waste water tank, and let the machine dry
You want to replace old clean water	Clean water tank	Empty it and refill to the FILL line with clean water before the next cycle

How to Drain the Baby Brezza Bottle Washer Pro Safely

Drain the Bottle Washer Pro by emptying the removable waste water tank and, before storage or moving, the clean water tank.

Step 1: Make Sure No Cycle Is Running

Wait for any wash, sterilize, or dry program to finish before removing either tank.
Set the Bottle Washer Pro on a stable counter near a sink.
You do not need to turn the unit on to empty the tanks. If you need to use the Bottle Washer Pro’s controls, press and hold the Power button for 3 seconds.

Step 2: Remove and Empty the Waste Water Tank

Find the waste water tank at the lower part of the Bottle Washer Pro base.
Grip its handle and pull the tank straight out, keeping it level as you carry it to the sink.
Pour the used water into the sink.
Do not pour waste water back into the clean water tank or into the wash chamber.

The waste water tank may contain cloudy water, milk residue, or detergent water after a cycle. That is normal; it is the tank’s job to collect used water so it does not remain inside the washer.

Step 3: Rinse, Dry, and Reinstall the Waste Water Tank

Rinse the inside of the empty waste water tank with clean water.
Pour out the rinse water.
Dry the tank, including its rim and exterior, before putting it back in the machine.
Slide the tank back into the base so it sits fully and evenly in place.

A reusable cloth wipe works well for drying the outside and rim of the tank before reinstalling it. Keeping the tank dry helps prevent leftover water from dripping onto the counter, shelf, or cabinet where the washer sits.

If you are about to run another cycle, check that the clean water tank is filled to its marked FILL line with clean water.

Step 4: Empty the Clean Water Tank for Storage or Moving

Emptying the clean water tank is optional after routine use, but it is a good idea before storing, relocating, or transporting the Bottle Washer Pro.

Lift the clean water tank out by its handle.
Carry it upright to the sink and pour out the remaining water.
Wipe the outside of the tank and let it dry before reinstalling it or setting it aside.

Emptying the removable tanks is the safe, intended way to remove water you can access.

What to Do If the Bottle Washer Pro Will Not Drain Completely

First, identify where the water is sitting. Water inside the waste water tank means the washer has moved used water where it belongs. Emptying that tank is the fix.

If there is water still visible in the main washing area after a completed cycle, use this order:

Check That the Waste Water Tank Is Seated Correctly

Remove the waste water tank, empty it, rinse it, dry it, and slide it back in evenly. Make sure it is not crooked or partially pulled out.

A tank that is not sitting properly can keep the machine from working as expected. Do not force it; pull it out and reinstall it gently.

Check the Clean Water Tank

If the clean water tank still contains water, remove it and empty it if you are storing the unit or replacing the water. Refill it with clean water to the FILL line before the next wash cycle.

Fresh water belongs only in the clean water tank, and used wash water belongs only in the waste water tank.

Do Not Try to Force-Drain the Base

Do not shake, invert, or disassemble the Bottle Washer Pro to remove water from inside its base. Do not poke into openings with utensils, wire, or bottle brushes.

If standing water remains in the wash chamber after a completed cycle and the tanks are correctly seated, stop using the machine and contact Baby Brezza customer support. Have the model name, any error code, and a clear description of where the water remains ready when you contact them.

Drain the Bottle Washer Pro Before Storage or Travel

A Bottle Washer Pro is easier to store cleanly when both tanks are empty and dry.

Empty the waste water tank into the sink.
Rinse and dry the waste water tank.
Empty the clean water tank.
Remove bottles, nipples, caps, and other loose parts from the racks.
Wipe up any water on the outside of the unit.
Leave the lid open long enough for the inside to air-dry before closing the machine for storage.
Carry the washer by supporting it from the base rather than the lid or tank handles.

Emptying both tanks before a move helps prevent spills in a car, closet, or storage bin.

Prevent Water and Residue Buildup

A few small habits make draining and cleanup easier:

Rinse milk, formula, other liquids, and food residue from bottles and accessories before placing them in the washer.
Use detergent tablets made for the Baby Brezza Bottle Washer Pro. Do not use household dishwasher detergent in the machine.
Wipe any splashes from the counter and the outside of the base before they dry.

These steps reduce lingering odors and make it easier to see whether the machine has transferred water normally during the next cycle.

Frequently Asked Questions

Where is the drain plug on a Baby Brezza Bottle Washer Pro?

There is no drain plug you need to use for normal emptying. Remove the waste water tank from the lower base of the machine, carry it to the sink, and pour out the collected water.

Do I have to turn on the Bottle Washer Pro to drain it?

No. You can remove and empty the water tanks while the machine is inactive. If you need to turn the Bottle Washer Pro on before using its controls, press and hold the Power button for 3 seconds.

How do I get all the water out of a Baby Brezza Bottle Washer Pro?

Empty the waste water tank for used water, then remove and empty the clean water tank if you are storing or moving the machine. Rinse and dry the waste water tank, and keep the appliance upright rather than tipping it over.

Why is there still water in my Bottle Washer Pro after a cycle?

Water in the waste water tank is expected because that tank collects the used wash water. If water remains in the main washing area after the cycle is complete, empty and reseat the waste water tank, check the clean water tank, and contact Baby Brezza support if the problem continues.

What does an E4 error mean on a Baby Brezza Bottle Washer Pro?

An E4 error should not be treated as a simple drain reminder. Do not try to force-drain the appliance. Empty, rinse, dry, and reinstall the waste water tank, then contact Baby Brezza support if the code remains or water is left in the wash chamber.
