Frequently Asked Questions - DG15602 SIEMENS

How do I install the Siemens DG15602 water heater?

Installation must be done by a qualified professional. Mount the unit on a wall, connect the water supply to the G 1/2 inlet, and plug into a 220-240 V grounded outlet. Ensure the device is splash-proof (IP24).

Can I adjust the water temperature?

Yes, the DG15602 features an electronic control with adjustable temperature range from 35 °C to 60 °C. Use the knob or buttons to set your desired water temperature.

What is the maximum flow rate?

The maximum flow rate is approximately 3.5 liters per minute at a temperature rise of 35 °C. At lower temperature rises, the flow rate can be higher.

Does this water heater work with low water pressure?

The Siemens DG15602 requires a minimum water pressure of 0.2 bar to operate correctly. If pressure is too low, the unit may not activate.

How do I clean or descale the water heater?

Descaling is recommended every 2 years. Use a descaling solution for electric water heaters. Follow the instructions: disconnect power, drain the unit, fill with descaling solution, let it sit, then rinse thoroughly.

The device includes thermal overload protection, an anti-freeze function, and IP24 splash-proof rating. It also has a safety pressure relief valve.

Can I use this water heater for a shower?

Yes, the DG15602 is suitable for a single shower or sink. For a higher flow rate, consider a more powerful model. Ensure the water pressure is adequate.

What does the error code E1 mean?

Error code E1 typically indicates a overheating or sensor malfunction. Turn off the unit, wait a few minutes, and restart. If it persists, contact service.

Is the heating element replaceable?

Yes, the heating element is a standard spare part and can be replaced by a technician. Siemens offers spare parts for the DG15602.

How much does this water heater cost to run?

At 6 kW and 220 V, the unit consumes about 0.1 kWh per minute of operation. Actual cost depends on your electricity rate and usage.

Operating the appliance

Open circuit operation (unpressurised): Always keep the spout free. Do not use perlators.

Water drips out of the spout during heating.

Closed circuit operation (pressure-resistant): Water drips out of the safety valve overflow during heating.

■Switch on the heater with the temperature selector switch.
The hot water temperature can be limited between position O and position III (see „Limiting the water temperature“, page 12).
■ Turn the temperature selector switch to position "O" to stop the heater.

Setting the water temperature

0 Off

* In this position the appliance is additionally protected against frost damage.
I Recommended setting for optimum energy saving ( ≈ 35 ^ C)
e Setting for the average hot-water requirement, e. g. for washing dishes (at ≈ 55 °C)
III Setting for hot water and greater warm water requirement, e. g. for cleaning ( ≈ 75 ^ C)

The specified temperatures are average values. They may vary according to local conditions.

Note: Most efficient operation results with the recommended setting I ( ≈ 35^ ). In setting e there is no longer any growth of legionnaire's disease bacteria. Legionnaire's disease bacteria are killed in setting III.

Cleaning

■Simply wipe the appliance and mixer tap with a damp cloth. Do not use acidic or abrasive cleaning materials.

Maintenance for the customer

If required, unscrew the shower head or outlet pipe and descale with a commercially available descaler or household vinegar.
■ Only pressure-resistant operation: The safety valve must be operated regularly to verify its function and to descale the valve.
When the water flows out of the hot water tap much more slowly with the tap fully open, this is an indication that the appliance requires dechalking. Call a specialist immediately otherwise the water heater could be subjected to high pressures.

Decalcifying, internal cleaning and repairs to the appliance may only be performed by one of our authorised customer service representatives.

A fault, what to do?
