Abstract
WX Eri is an eclipsing binary system for which one component was reported to show Scuti type pulsations with periods close to integer fractions of the orbital period. This makes it an interesting candidate for investigating the interaction between binarity and pulsation and a potential new member of the recently defined group of mass-accreting pulsating components (gainers) in semi-detached Algol binaries called "oscillating EA" stars. We present new photometric time-series observations of this star. The Wilson-Devinney code was applied to find the best fitting model for the eclipsing binary's light curve. The aim of the observations was to investigate the short-period  Scuti type pulsations of WX Eri. However, no evidence for the presence of such oscillations was found in our data.
