Countertop dishwasher water light: check the fill sequence
On the COMFEE CDC17P2AWW, turn the dishwasher on before filling, then add water slowly until it beeps rapidly for three seconds and the tap symbol switches off. If a supposedly full tank still triggers a warning, stop pouring and check the exact model’s instructions.
A pitcher count is not the full-tank signal
It is easy to lose track while carrying water from the sink. The more useful check is the indicator described in your own manual. COMFEE’s quick-start guide explicitly puts power-on before tank filling; the tank-full acknowledgement is not simply a guessed number of pitchers.
HAVA’s US FAQ describes three beeps when its tank is full. Do not turn that into an instruction to keep adding water indefinitely. If water is at the fill opening, spills, or the expected signal never occurs, stop and ask support about that symptom.
Separate three different situations
| Situation | What it changes |
|---|---|
| Manual tank filling | Use the powered fill sequence and full indication for that model. |
| Optional faucet inlet connected | A closed supply or inlet problem is different from forgetting a pitcher. Follow the inlet section of the manual. |
| A numbered error code rather than a reminder icon | Look up that exact code. Do not assume every water-related symbol means an empty tank. |
What to record before contacting support
Note the model label, whether you are using tank or faucet supply, when the warning appears, and whether the expected beep ever occurs. A short description such as “CDC17P2AWW, manual fill, powered on first, no three-second beep, warning before Start” is more useful than “water error.” A photograph of the display can prevent confusion between a reminder and a fault.
Do not bypass a sensor, remove panels or repeatedly overfill the tank. A reminder that persists after the documented sequence may need manufacturer diagnosis. This guide does not identify a sensor failure from the icon alone.
Considering a tank model before buying?
Imagine the repeated filling trip in your actual kitchen. You need comfortable access to the fill opening as well as a route for the drain hose. A tank avoids a faucet connection for incoming water; it does not remove the need to empty wash water. A convenient daily routine matters more than the label “no installation.”
Questions that come up next
Can I fill while the unit is switched off?
Use the matching manual. The CDC17P2AWW quick-start instructions specifically say to turn it on before adding water.
Does the tap icon prove the tank sensor is broken?
No. First distinguish a fill reminder, a supply problem and a model-specific error code.
Your next useful step
Use the exact-model fill sequence; if it still fails, send support the observations above.

This is research-based guidance, not a hands-on test or an individual repair diagnosis. Match the exact model and current manual; where instructions conflict, ask the manufacturer.
