HumminGuru Water tank

In an ultrasonic cleaning machine, the water makes a round trip with each cycle: it leaves a removable tank, fills the basin where the record rotates, then returns to the tank once draining is complete. This genuine HumminGuru tank replaces the one in your machine if it is cracked, lost or clouded. You can also use it alongside the first to keep two separate batches of water, one for washing and the other for rinsing.

Four hundred millilitres with markings for each record size

The tank holds a maximum of 400 ml, the amount the cleaning basin can accommodate. Its wall has four graduations (100, 200, 300 and 400 ml) and two level marks. The first is for 30 cm and 25 cm records, the second for 17 cm 45 rpm records. These marks serve as a starting point. The correct water level just covers the smooth band between the last track and the label: the ultrasound then reaches the entire groove without wetting the paper. A thick, slightly warped record or one with an unusually sized label may require a few millilitres more or less. The graduations then help you use the right amount from one session to the next.

The lid has a removable holder for a water filter. This filter slides in folded in half and traps the larger particles loosened from the record during cleaning. The filter cartridge is not supplied with this tank: the one from your machine can be moved from one tank to the other. If you prefer to work without a filter, simply remove the holder from the lid.

The water’s journey between the tank and the cleaning basin

Fill the tank to the desired level, pour the water into the basin, then put the empty tank back into its slot on the side of the machine. The NOVA comes with a funnel for pouring water without splashing the mechanism. At the end of cleaning, draining returns the water from the basin to the tank in around forty seconds, before fan drying begins. The tank therefore also serves as a collection container. As it is transparent, you can see the condition of the used water at a glance: if it is cloudy or full of particles, it needs changing.

The machine checks that the tank and its lid are present before starting, and no cycle will run without them. On the NOVA, removing the tank during a programme turns on a steady red indicator light and stops the machine. It returns to standby as soon as the tank is put back in place.

Two tanks to separate washing and rinsing

With a single tank, the same water is used from one record to the next until it is replaced. A second tank changes how a session is organised. The first holds the cleaning water: distilled water with a few drops of surfactant, an agent that reduces the water’s surface tension so it reaches the bottom of the groove more easily. The second contains only distilled water. After cleaning and draining, swap the tanks and run a short cycle with clean water. This rinse removes the last traces of cleaning solution before drying, and each batch of water stays in its own tank from one session to the next.

This tank also serves as a spare part. Over the years, the plastic can become cloudy and lose the transparency that lets you monitor the water. A cracked tank or a lid that does not close properly lets water leak near the electronics. The same tank fits the original HumminGuru (HG01) and the NOVA (HG05): if you switch from one model to the other, your tanks remain usable.

Care and precautions for a plastic tank

Empty the tank after each session. Then rinse the body, lid, filter holder and filter itself with clean water and leave them to air-dry. Do not use a dishwasher, microwave or any other heat source. Heated plastic can warp, leaving the tank unable to fit properly into the machine.

The water you pour in must be cold or at room temperature, never hot. The ultrasound already raises the bath temperature over successive cycles, and the machine stops cleaning as soon as the water reaches 55 °C. Use distilled, demineralised or deionised water. Tap water, especially hard water, leaves deposits on records and in the internal pipes.
