Question 2

How to avoid stains and marks on glasses with the Colged SteelTech 48?

Accepted Answer

Stains on glasses after washing in the Colged SteelTech 48 are often related to hard water, insufficient rinsing, or product dosing. Here’s how to correct this issue:

Check and adjust the regeneration system

The manual recommends adding about 300 g of granular salt when the message "SA Lt" appears. Insufficient salt does not treat hard water, the main cause of limescale deposits and stains on glasses. Ensure that the salt reservoir is regularly filled.

Select the right washing program

For glasses, the SteelTech 48 offers the programs G2 (standard glasses) or G3 (intensive glasses). If stains persist with G2, try G3 which provides a more powerful rinse.

Check filters and spray arms

The manual recommends regular cleaning of filters, arms, and dispensers. Limescale deposits or residues in these elements reduce rinsing efficiency. Clean them after each difficult wash.

Use a suitable rinse aid

Complement your detergent with a rinse aid (liquid or tablet). This significantly improves the clarity of glasses by eliminating water droplets that form marks.

Follow usage precautions

The manual states to never use chlorine-based or hypochlorite detergents, which can leave deposits. Prefer standard detergents recommended for hard water.

Question 3

The dishwasher does not drain water at the end of the cycle

Accepted Answer

First, identify the type of your Toptech 36: The Colged Toptech 36 dishwasher comes in two configurations: without a drain pump (gravity drainage) or with a drain pump (optional). If your machine has not been used for a long time or if you suspect a malfunction, first check that the drain hose is not bent, crushed, or blocked, and that it is positioned at a maximum height of 1 meter for versions with a pump.

If your Toptech 36 has a drain cycle (pump version): With the machine running, press the program selection button (button 3) until the ProDrain program appears - this is the specific drain cycle for this model. Then press the START button (button 4) to start the draining process. At the end of the cycle, the machine will automatically turn off and only the STANDBY light (5) will remain on. For a thorough cleaning, you can use the ProClean program instead, which combines draining and an internal circuit self-cleaning - ideal if the water only drains partially.

If your Toptech 36 does not have a drain pump: Turn off the machine. Remove the full filter (Fig. 7A), then pull and remove the overflow hose (Fig. 7). Wait for the basin to completely drain by gravity - this process may take several minutes. Once drained, check and clean the basin filter if it contains debris.

Common cause: clogged filters: The failure to drain may also result from dirty filters. At the end of each day, remove and clean all filters from the Toptech 36 - food residues or mineral crystals can block the drainage circuit. Also check the wash and rinse arms, as their nozzles may be blocked by deposits, disrupting the final drainage.

Additional quick checks: Ensure that the external drainage well is not full or blocked - water can only drain if the well is accessible. For machines without a pump, the drainage well must be lower than the base of the appliance. If after these checks and cleaning the filters the problem persists, technical intervention will be necessary to inspect the drain pump or the internal drainage system.
